Speculation and hearsay are excluded from this list. Everything you see here is an undisputed action or statement by Donald J. Trump or his administration, with sources provided.
During the September 29 presidential debate, moderator Chris Wallace asked Trump if he would be willing to denounce white supremacists right there on the stage. Trump initially dodged the question and attempted to change the subject. When pressed further and was specifically asked to denounce the Proud Boys and white supremacists, Trump said "Stand back and stand by," and then changed the subject to Antifa.
The Proud Boys have adopted "Stand back and stand by" as an unofficial slogan, and are now selling merchandise with the statement. 
In August 2017, white supremacists and Neo-Nazis held a rally in Charlottesville, Virginia. This was not a rally where some white supremacists happened to show up - the rally was organized and attended solely by self-identified white supremacists and Neo-Nazis, with the goal of unifying the American white nationalist movement 
The rally was attended by David Duke and other members of the Ku Klux Klan. Attendees could be heard chanting "Jews will not replace us", "Blood and Soil" (a Nazi slogan ) and "We love Russia".
These white nationalists believe that Trump is fighting for their beliefs. In an interview on the morning of the rally, David Duke said, "We are determined to take our country back. We're going to fulfill the promises of Donald Trump. That’s why we voted for Donald Trump, because he said he’s going to take our country back."
On August 15, 2017, Trump held a press conference where he was hesitent to condemn the rally attendees, and stated, "you had some very bad people in that group, but you also had people that were very fine people, on both sides."  Donald Trump is stating here, in no uncertain terms, that some white nationalists are very fine people.
The U.S. Department of Justice concluded that Arizona sheriff Joe Arpaio oversaw the "worst pattern of racial profiling in U.S. history". The illegal tactics that he was using included "extreme racial profiling and sadistic punishments that involved the torture, humiliation, and degradation of Latino inmates". 
Arpaio built a tent camp for migrant children which he once proudly referred to as a "concentration camp" . In this camp, Latinos were detained, often illegally, purely based on their appearance and assumed immigration status. In many instances, officers detained lawful Latino residents for hours, days, or weeks based on fabricated or exaggerated charges.Detainees faced gruesome conditions and egregiously inhumane practices :
Trump referred to Arpaio as an "American Patriot" 
"By pardoning Joe Arpaio, Donald Trump has sent another disturbing signal to an emboldened white nationalist movement that this White House supports racism and bigotry." According to ACLU deputy legal director Cecilia Wang, the pardon was "a presidential endorsement of racism". 
"Sheriff Arpaio has made public statements that a fact finder could interpret as endorsing racial profiling, such as stating that, even lacking 287(g) authority, his officers can detain people based upon 'their speech, what they look like, if they look like they came from another country'... Moreover, he acknowledges that MCSO provides no training to reduce the risk of racial profiling, stating 'if we do not racial profile, why would I do a training program?'"

On July 26, 2020, Trump retweeted a video showing one of his supporters riding a golf cart holding "Trump 2020" and "America First" signs. In the video, protestors shout taunts such as "Where's your white hood?" and the man responds by pumping his fist in the air and shouting "White power!" 
Trump retweeted the video, thanking "the great people of The Villages," the Florida retirement community where the video took place.
In response to the tweet, senator Tim Scott, the only black Republican senator, said "I think it's indefensible. We should take it down."
Former national security advisor John Bolton said it was "entirely possible that he tweeted tweeted this video because he saw the sign," but also admitted, "It may be that you can draw a conclusion that he heard it, and it was racist, and he tweeted it to promote the message. It's a legimiate conclusion to draw."
In 1989 a woman was brutally raped in Central Park, the point of memory loss, brain damage, extreme injury and a 12 day coma. In the same night, attacks by predominately black teenagers were reported in the Central Park area. NYPD arrested 14 teenagers, and charged 5 with the rape. During their interrogation, the 5 teenagers "confessed" to the rape after being coerced, attacked and denied their rights by NYPD. This case is historical, because it brought to light the seriousness of false and coerced confessions. Despite indisputable evidence, these teenagers were convicted of rape and served prison time. In 2001, a convicted murdered and serial rapist confessed to the rape, evidence proved his confession was genuine. It wasn't until 2002 that the Central Park 5 Falsely accused were released. 
Prior to conviction, though while strong evidence that the teenagers were innocent, Trump took out a full page ad, advocating for the return of the death penalty of these 5 teenagers . Trump stated on Larry King, "maybe hate is what we need if we're gonna get something done." 
In 2014, when the Central Park 5 sued the city of New York, Trump stated the settlement was "a disgrace", saying: "Settling doesn't mean innocence. [...] These young men do not exactly have the pasts of angels."  In 2016, Trump again maintained the Central Park 5 were guilty, despite proof they were not . In 2019, Trump again insisted "You have people on both sides of that. They admitted their guilt. If you look at Linda Fairstein and if you look at some of the prosecutors, they think that the city should never have settled that case. So we'll leave it at that." 
Trump never recanted his full page ad calling for the death penalty of the 5 falsely accused.
Trump Management actively denied housing and property to black tenants . Employees stated they were "discouraged rental to blacks" and they were "not allowed to rent to black tenants."  Prospective black tenants were sent to different offices than white renters.
Investigators sent test applicants to open listings and found that black applicants were informed that a listing had been filled. When a white applicant requested to rent the same unit directly afterwards, they were offered immediate move-in dates.
On his radio show in 2005, Trump Explained to listeners that he "wasn't particularly happy" with the show's most recent season, Trump said he was mulling "an idea that is fairly controversial — creating a team of successful African-Americans versus a team of successful whites. Whether people like that idea or not, it is somewhat reflective of our very vicious world." 
On the Laura Ingraham Show in March 2011, Trump said, "He doesn’t have a birth certificate, or if he does, there's something on that certificate that is very bad for him. Now, somebody told me—and I have no idea whether this is bad for him or not, but perhaps it would be—that where it says 'religion,' it might have 'Muslim.'" 
Even after Obama provided a copy of his birth certificate, in May 2012, Trump told Wolf Blitzer that "a lot of people" do not think it was an authentic certificate. In August 2012, he called the certificate a "fraud".
An 'extremely credible source' has called my office and told me that @BarackObama's birth certificate is a fraud.— Donald J. Trump (@realDonaldTrump) August 6, 2012
It wasn't until September 2016 that Trump finally acknowledged that Obama was born in the United States.
Trump has made several false claims about the reliability of mail-in voting, an option many Americans will choose to cast their votes safely during the COVID-19 pandemic. He is using these baseless claims to lay the groundwork for claiming a fraudulent election in the even that he loses.
Trump has repeated these baseless claims frequently, with no evidence to back up his claims.
RIGGED 2020 ELECTION: MILLIONS OF MAIL-IN BALLOTS WILL BE PRINTED BY FOREIGN COUNTRIES, AND OTHERS. IT WILL BE THE SCANDAL OF OUR TIMES!— Donald J. Trump (@realDonaldTrump) June 22, 2020
Intelligence agencies have found no evidence of any plot to counterfeit or forge mail ballots, and historically any fraud using mail ballots is extremely rare. 
At the Republican National Convention, despite being significantly behind in the polls, Trump said "The only way we're going to lose this election is if the election is rigged, remember that."
In a press briefing on September 23, Trump refused to commit to a peaceful transfer of power if he loses the election, again claiming falsely that mail-in ballots would be a problem.
"Should we go back to 16 years? Congress, can we have that extended?"
"I was going to joke, General, and say at least for 10, or 14 years, but we would cause bedlam if I said...so we'll say six."
"Don't forget China's great, and Xi is a great gentleman. He is now president for life. President for life! And he was able to do that, I think it's great. Maybe we'll give that a shot some day."

"And then after that we'll go for another four years because you know what, they spied on my campaign. We should get a re-do."
This event was the basis for the 2019 impeachment of Donald Trump.
In September 2019, a whistleblower complaint raised concerns about Trump using his presidential powers to solicit foreign intervention in the US electoral process. The complaint was specifically around a phone call between Trump and Ukrainian president Volodymyr Zelensky, in which Trump asked Zelensky to open investigations into Joe Biden and his son, Hunter Biden. The request came directly after discussing congressionally-mandad military funds to Ukraine, after which Trump said, "I would like you to do us a favor though." 
The White House has confirmed several of the allegations, and has provided a non-verbatim transcript of the phone call. 
In January 2020, the Government Accountability Office, a non-partisan watchdog agency, concluded that the White House broke federal law by withholding the aid. Specifically, the White House violated the Impoundment Control Act, which states that the government "does not permit OMB to withhold funds for policy reasons." 
In a news conference in July 2016, Trump said: "Russia, if you're listening, I hope you're able to find the 30,000 emails that are missing. I think you will probably be rewarded mightily by our press."
According to indictments issued during Robert Mueller's investigation, "the conspirators attempted after-hours to spearphish for the first time email accounts at a domain hosted by a third-party provider and used by Clinton’s personal office." 
Roger Stone came under investigation for his ties to Russia and WikiLeaks during the 2016 election. Stone appeared to have insider information on the 20,000 leaked emails belonging to Clinton campaign chairman John Podesta. When questioned by Congress on the source of his information, Stone claimed that his source was radio host Randy Credico. Prosecutors later found evidence that his true source was Jerome Corsi, a right wing conspiracy theorist. In an email dated August 2, 2016, Corsi told Stone that WikiLeaks planned to release "very damaging" information about Clinton.
Randy Credico testified that Stone had threatened him and his therapy dog in an attempt to prevent him from testifying before Congress. In an apparent reference to the "Godfather" movies, Stone said, "I'm going to take that dog away from you. Not a fucking thing you can do about it either because you are a weak piece of shit." In another exchange, Stone said, "Let's get it on. Prepare to die,cocksucker."
These threats were successful, and resulted in Credico invoking his Fifth Amendment right to avoid testifying before the Committee.
Stone also claimed that he never had any written communications referencing Assange, when in fact several text messages and emails were found referencing WikiLeaks and Corsi. 
Stone was also convicted of obstructing the Russia investigation. He claimed that he has nothing to do with Russia, however several emails were found between Stone and the Russian hacker accused of the cyberattack on the DNC. 
Stone is a loyal Trump supporter, and has promised to remain loyal to the President. "I will never roll on Donald Trump."  In an interview with NBC's Howard Fineman, Stone said, "I had 29 or 30 conversations with Trump during the campaign period,” he reminded me. “He knows I was under enormous pressure to turn on him. It would have eased my situation considerably. But I didn’t. They wanted me to play Judas. I refused." 
Trump's decision to commute Stone's sentence is unprecedented, and spurred an op-ed by Rober Mueller where he stated, "When a subject lies to investigators, it strikes at the core of the government’s efforts to find the truth and hold wrongdoers accountable. It may ultimately impede those efforts."
Senator Mitt Romney called the commutation "Unprecedented, historic corruption"
Unprecedented, historic corruption: an American president commutes the sentence of a person convicted by a jury of lying to shield that very president.— Mitt Romney (@MittRomney) July 11, 2020
Michael Cohen, who had been Trump's personal attorney since 2006, is currently serving a 3 year prison sentence for tax evasion, campaign finance violations, and other crimes. His campaign finance violation conviction stems from the $130,000 in hush money that Cohen paid to Stormy Daniels, at Trump's direction, in exchange for her silence regarding her affair with Trump.
Trump is an unindicted co-conspirator in these charges, as a sitting president cannot be indicted per Department of Justice policy. 
In summary, Trump committed a felony campaign finance violation by instructing his lawyer to make a payment for the purpose of influencing an election. He has not yet been indicted for this crime as a sitting president cannot be indicted.
In June 2020, the National Guard used tear gas and rubber bullets to clear a crowd of peaceful protestors Lafayette Park. The crowd was protesting the murder of George Floyd, which had happened a week earlier in Minneapolis.
The church had not been notified about the visit, and the church leadership opposed using their church as a backdrop for Trump's message. "That is the most sacred text of the Judeo-Christian tradition. It speaks messages of love, of God, love of neighbor. I was outraged that he felt that he had the license to do that, and that he would abuse our sacred symbols and our sacred space in that way," said Right Rev. Mariann Edgar Budde, Episcopal bishop with oversight responsibilities for the church. 
In an interview with Bloomberg Politics, Trump was asked to name one or two of his favorite verses. He refused to cite a single verse. 
In a July 2015 interview with Anderson Cooper, Trump was questioned on his views regarding repentance, a core tenet of Christian faith. Trump responded that he has never asked for forgiveness from God because he does not make any mistakes.
In 2019, the Trump administration announced changes to the way the Endangered Species act will be applied. The changes make it easier to remove species from the list and weaken protections for threatened species, the classification below endangered. 
The changes also allow regulators to consider the economic impact on protecting a species during the decision process.
The Trump administration also loosened the definition of "forseeable future" when defining risks to a species, which allows regulators to ignore the effects of climate change on species continued survival.

January 21, 2015: In a radio interview with Hugh Hewitt, Trump said "I’m not a believer in global warming. And I’m not a believer in man-made global warming." 
In March 2020, at the request of auto manufacturers, the Trump administration finalized its rollback of Obama-era climate regulations on emissions standards. The new rules reduces the 5% increase in carbon dioxide emissions standards to 1.5%. The Trump administration originally proposed freezing the standards completely, but compromised at the 1.5% after pushback from both environmental groups and the auto makers who requested the rollbacks in the first place.
Critics argue that not only will the new rule add almost a billion metric tons of CO2 to the atmosphere, the reduced emissions standards will also end up costing consumers about 80 billion more gallons of gas.
The EPA analyzed that there would also be more premature deaths from increased air pollution due to the new rule. 
In June 2020, Trump signed an executive order aimed at allowing federal agencies to sidestep standard requirements of environmental regulations such as the Clean Air and Endangered Species Acts. 
The order is aimed at boosing the econimic recovery from the COVID-19 pandemic. Environmental laws do allow for exemptions under emergency conditions, however, these have historically been reserved for natural disasters, and not for economic reasons.
In August 2020, the Trump administration announced that it will open up the Arctic National Wildlife Refuge to drilling. This will allow leasing on the undisturbed wilderness, which is home to migrating caribou, polar bears and foxes. It is estimated that this will release more than 4.3 billion metric tons of carbon dioxide into the atmosphere, equal to about 3/4 of US annual emissions. 
In May 2019, the Trump administration rolled back Obama-era safety regulations for offshore drilling. The rollback affects rules aimed at preventing offshore oil and gas wells from "blowing out," or suddenly releasing an uncontrollable amount of crude oil.
The rolled-back rules were put in place in 2011, after the Deepwater Horizon disaster, an explosion which killed 11 workoers and spilled 4 million barrels into the Gulf of Mexico over 87 days. The new rules included requirements for the design of drilling components as well as monitoring and inspection regulations. 
In August 2020, the Trump administration announced plans to lift Obama-era controls on the release of methane gas. The new rule eliminates federal mandates requiring oil and gas companies to install technology to "detect and fix methand leaks from wells, pipelines, and storage sites." 
Many oil and gas companies opposed this change. Methane is the main ingredient in natural gas, and incentivizing companies to prevent leaks helps promote natural gas as a clean energy. 
In 2019, the Trump administration planned to strip protections on the habitat of the sage grouse. The sage grouse is referred to as a "canary in the coal mine" for the environment it habitates - when the sage grouse population is declining, the surrounding ecosystem is likely also declining. 
The Trump administration plan would lead to increased oil and gas leases, drilling permits, roads, pipelines, power lines, and more in the protected lands.
A federal judge ultimately blocked the plan, arguing that the administration "failed to consider reasonable alternatives and did not thoroughly examine the environmental consequences of its actions." 
In 2005, Donald Trump bragged to television host Billy Bush that his celebrity status allowed him to grope and kiss women without their consent.
"I don’t even wait. And when you’re a star, they let you do it, you can do anything… grab them by the pussy." 
"You know they’re standing there with no clothes. Is everybody OK? And you see these incredible looking women. And so I sort of get away with things like that." 
Contestants described Trump's behavior as "creepy" and "shocking". Some contestants were as young as 15 years old.
Former contestant Tasha Dixon said that Trump pressured women to "fawn over him, go walk up to him, talk to him, get his attention" while still not fully dressed, and said that this made contestants feel awkward and physically vulnerable.

In a presidential debate on March 3, 2016, Trump was asked what he would do if the military refused to carry out his illegal orders. He responded, "They won't refuse. They're not going to refuse me. Believe me." When pressed, he doubled down, "If I say do it, they're going to do it." 
A common misconception is that family separation was started under the Obama administration. While it is true that the holding facilities were built under Obama's administration, their purpose was originally to hold children who had arrived unaccompanied at the border. This was to provide temporary shelter until they could be relocated to a family member. 
The Trump administration implemented a new family separation policy for the purpose of punishing families arriving at the border. This has affected families immigrating illegally, but has also affected families who are legally seeking asylum. 
....These THUGS are dishonoring the memory of George Floyd, and I won’t let that happen. Just spoke to Governor Tim Walz and told him that the Military is with him all the way.

"If you see somebody getting ready to throw a tomato, knock the crap out of them. Seriously. Okay? Just knock the hell out of them. I promise you, I will pay for their legal fees." 
At the 2015 Family Leadership Summit in Iowa, Trump was asked if it was appropriate that he called John McCain a "dummy". Trump responds with a tirade, describing McCain as a loser for failing to win the 2008 election. He then goes on to say that McCain is only considered a war hero because he was captured. .
Trump received heavy criticism for leaving the hospital in a motorcade while infected with COVID-19, putting the Secret Service detail at risk. At least two military service members who have come into contact with Trump have since tested positive for COVID-19. 
In 2018, Trump was scheduled to attend a commemoration in France for US military members killed during World War One. He canceled last-minute due to rain. 
Ben Rhodes, President Barack Obama's deputy national security adviser for strategic communications, said this was an invalid excuse:

February 28, 2020: Trump tells his supporters at a rally that the coronavirus is a Democrat hoax: "Now the Democrats are politicizing the coronavirus, you know that, right? Coronavirus, they’re politicizing it. We did one of the great jobs. You say, ‘How’s President Trump doing?’ They go, ‘Oh, not good, not good.’ They have no clue. They don’t have any clue. They can’t even count their votes in Iowa."" "They tried the impeachment hoax. That was on a perfect conversation. They tried anything. They tried it over and over. They’d been doing it since you got in. It’s all turning. They lost. It’s all turning. Think of it. Think of it. And this is their new hoax."

At a rally in Pennsylvania, Trump mocked Biden in front of a mostly maskless crowd. But did you ever see a man that likes a mask as much as him? And then he makes a speech, and he always has it - not always, but a lot of times, he has it hanging down. Because, you know what, it gives him a feeling of security. If I were a psychiatrist — right? I'd say, this guy's got some big issues. Hanging down." 
Trump mocked Biden again at the September 29 presidential debate: "Every time you see him, he's got a mask. He could be speaking 200ft away and he shows up with the biggest mask I've ever seen."  Trump was diagnosed with COVID-19 two days later. 
There are 19 Trump campaign rallies for 2020, all occuring well into the COVID-19 pandemic . Trump defies his own administration's health guidelines, and in many cases he defies local gathering restrictions . Masks are not required, nor is he requiring that attendees practice social distancing.
The Cleveland Clinic, venue for the September 2019 presidential debate, required that all attendees wear face coverings throughout the debate. The Trump family initially came in wearing masks, but all removed them as soon as they were seated. A safety person for the Cleveland Clinic offered them masks, and they were waved away. Trump's guests were the only attendees spotted not wearing masks. 
Trump was hospitalized on Friday, October 2 after testing positive for COVID-19. When he was discharged on Monday, October 5, he immediately released a tweet encouraging followers not to fear the virus that has killed over 210,000 Americans and has caused permanent health defects for many others.
I will be leaving the great Walter Reed Medical Center today at 6:30 P.M. Feeling really good! Don’t be afraid of Covid. Don’t let it dominate your life. We have developed, under the Trump Administration, some really great drugs & knowledge. I feel better than I did 20 years ago!— Donald J. Trump (@realDonaldTrump) October 5, 2020
Presidents have traditionally divested their shares in any businesses while president. Donald Trump has refused to do so, and instead handed control to his two sons. According to the Director of the U.S. Office of Government Ethics, Trump’s arrangement "doesn’t meet the standards that the best of his nominees are meeting and that every President in the past four decades has met." 
The Washington Post has kept a running tally of each Presidential visit to a Trump-owned property. As of September, Trump has visited his own properties 274 times. This equates to over 6 visits per month on average throughout his presidency.
Government documents show that the Trump Organization has charged as much as $650 per room per night. In one case, records show that the Trump Organization charged the Secret Service $17,000 per month to rent a 3 bedroom cottage, a rate that is unusually high for comparable rental homes in that area. 
In Spring of 2020, documents show that Trump's club in Bedminster, New Jersey charged the Secret Service at least $21,800 to rent rooms while the club was off-limits to guests. The president did not visit the club during this time period. 
In October 2019, Trump announced that the 2020 G-7 Summit would be hosted by his own company, at the Trump National Doral Miami gold resort in Florida. The resort reported a 69% drop in net operating income from 2015 to 2017 and was struggling to fill vacancies.
Only after immense public backlash did Trump reverse course and rescind the announcement.
