Four Trump campaign officials have now been charged or entered guilty pleas as a result of the special counsel investigation into Russian interference in the 2016 election.

Moscow, at the behest of Russian President Vladimir Putin, allegedly waged a sustained influence operation in support of Donald Trump’s campaign for president. Major questions remain about the degree of interaction between Trump associates and Russian operatives.


Trump is now facing a special prosecutor — former FBI Director Robert Mueller — who is delving into the allegations of Russian meddling and possible collusion between Trump's campaign and the Kremlin.

Here’s what we know so far based on news reports, public statements, court documents and the U.S. government’s unclassified report on Russian election interference.

Possibly it was Russia but they are totally denying it. … But they're saying it wasn't them. The other side says it is them. And we're going to go through that arguing for probably for 50 years and nobody is ever going to know. Probably was Russia.”

"He is an absolute leader of the presidential race, as we see it today. He says that he wants to move to another level relations, a deeper level of relations with Russia … How can we not welcome that? Of course, we welcome it.”

Trump responds with praise of his own.

"It is always a great honor to be so nicely complimented by a man so highly respected within his own country and beyond," Trump says in a statement. "I have always felt that Russia and the United States should be able to work well with each other towards defeating terrorism and restoring world peace, not to mention trade and all of the other benefits derived from mutual respect."

The professor says he has just returned from meeting with high-level Russian government officials in Moscow and that “he (the Professor) learned that that the Russians had obtained ‘dirt’ on then-candidate Clinton,” according to court documents.

The Washington Post reports the same day: “The Trump campaign worked behind the scenes last week to make sure the new Republican platform won’t call for giving weapons to Ukraine to fight Russian and rebel forces, contradicting the view of almost all Republican foreign policy leaders in Washington.”

“She doesn’t know if it’s the Russians doing the hacking,” Trump responds. “Maybe there is no hacking. But they always blame Russia. And the reason they blame Russia because they think they’re trying to tarnish me with Russia. I know nothing about Russia. I know — I know about Russia, but I know nothing about the inner workings of Russia. I don’t deal there. I have no businesses there. I have no loans from Russia.”

Feb. 16: Trump again calls the Russia controversy “fake news” and said that the Times story from Feb. 14 was “a joke.”

Trump also states: “I have nothing to do with Russia. I told you, I have no deals there, I have no anything. Now, when WikiLeaks, which I had nothing to do with, comes out and happens to give, they’re not giving classified information.”

He also says: “I’m here today is to tell you the whole Russian thing, that’s a ruse. That’s a ruse. And by the way, it would be great if we could get along with Russia, just so you understand that. … I didn’t do anything for Russia. … If we could get along with Russia, that’s a positive thing. … I would love to be able to get along with Russia. … If we have a good relationship with Russia, believe me, that’s a good thing, not a bad thing.”

March 3: CNN reports on additional meetings that took place between Trump associates and Kislyak.

Trump posts an old picture of Sen. Chuck Schumer eating doughnuts with Vladimir Putin on Twitter and writes : “We should start an immediate investigation into @SenSchumer and his ties to Russia and Putin. A total hypocrite!”

Kislyak cancels plans to attend the March 4 Gridiron Dinner.

March 4: Trump accuses Obama of having ordered a tapping of the phones at Trump Tower during the campaign, writing in a series of tweets: “Terrible! Just found out that Obama had my "wires tapped" in Trump Tower just before the victory. Nothing found. This is McCarthyism! … Just out: The same Russian Ambassador that met Jeff Sessions visited the Obama White House 22 times, and 4 times last year alone. … Is it legal for a sitting President to be "wire tapping" a race for president prior to an election? Turned down by court earlier. A NEW LOW! … I'd bet a good lawyer could make a great case out of the fact that President Obama was tapping my phones in October, just prior to Election! … How low has President Obama gone to tapp my phones during the very sacred election process. This is Nixon/Watergate. Bad (or sick) guy!”

Obama denied the allegations through a spokesman. Comey asks the Justice Department to reject the claim, but no rejection is issued. The claims appeared to be based on a talk radio segment and a Breitbart article about the talk radio segment. The White House declines to offer any evidence to back up the claims, and the next day calls on Congress to investigate and says it will not comment further.

Trump writes on Twitter: “James Clapper and others stated that there is no evidence Potus colluded with Russia. This story is FAKE NEWS and everyone knows it! … The Democrats made up and pushed the Russian story as an excuse for running a terrible campaign. Big advantage in Electoral College & lost! … The real story that Congress, the FBI and all others should be looking into is the leaking of Classified information. Must find leaker now! … What about all of the contact with the Clinton campaign and the Russians? Also, is it true that the DNC would not let the FBI in to look?”

March 22: The Associated Press reports that Manafort previously secretly worked on behalf of a Russian billionaire to enhance the image of Putin and the Russian government in the West.

At the White House, Spicer downplays Manafort’s role in the campaign and declares: “And to be clear, the president has no personal financial dealings with Russia. His ties are limited to hosting a contest in Russia once, and selling a Palm Beach home to a businessman in 2005. That's it.”

When asked if Manafort ever encouraged the campaign to take a more pro-Russia position, Spicer responds: “Not that I’m aware of.”

CNN reports that night: “The FBI has information that indicates associates of President Donald Trump communicated with suspected Russian operatives to possibly coordinate the release of information damaging to Hillary Clinton's campaign, US officials told CNN. This is partly what FBI Director James Comey was referring to when he made a bombshell announcement Monday before Congress that the FBI is investigating the Trump campaign's ties to Russia, according to one source.”

March 23: Spicer mocks the CNN report, saying the use of the term “associates” is too broad.

A total scam!”

April 6: Rep Devin Nunes (R-Calif.) steps aside from the House investigation into Russian meddling in the 2016 election after an odd series of events in which he alerted the White House to potential unmasking of transition officials in intelligence reports before giving the news to his fellow committee members.

April 13: “We’re not getting along with Russia at all … we may be at an all-time low,” Trump says during a press conference at the White House with the NATO secretary general. Tillerson and Putin met the same day in Moscow.

Yates confirms that she informed the White House that Flynn was “compromised” weeks before news broke that Flynn had misled the vice president and was fired.

Trump tweets: “Director Clapper reiterated what everybody, including the fake media already knows- there is ‘no evidence’ of collusion w/ Russia and Trump.”

Trump later tweets: “The Russia-Trump collusion story is a total hoax, when will this taxpayer funded charade end?”

May 9: Trump fires FBI Director James Comey. In the letter announcing his termination, Trump writes: “While I greatly appreciate you informing me, on three separate occasions, that I am not under investigation, I nevertheless concur with the judgment of the Department of Justice that you are not able to effectively lead the Bureau.”

The White House’s official explanation is that Deputy Attorney General Rod Rosenstein recommended the termination in a memo dated May 9, and Sessions affirmed the recommendation in a letter to Trump.

The firing leads to outcry among Democrats and Republicans alike, with many renewing calls for an independent investigation into potential collusion between Trump’s campaign and the Russian government.

May 10: Trump meets with Russian Foreign Minister Sergey Lavrov in the Oval Office. Lavrov met earlier in the day with Secretary of State Rex Tillerson and joked about Comey’s firing.

May 11: Trump writes on Twitter: “Russia must be laughing up their sleeves watching as the U.S. tears itself apart over a Democrat EXCUSE for losing the election.”

Trump tells NBC’s Lester Holt of his decision to fire Comey: “When I decided to just do it, I said to myself, I said you know, this Russia thing with Trump and Russia is a made up story, it's an excuse by the Democrats for having lost an election that they should have won."

May 12: Trump writes on Twitter: “Again, the story that there was collusion between the Russians & Trump campaign was fabricated by Dems as an excuse for losing the election. … When James Clapper himself, and virtually everyone else with knowledge of the witch hunt, says there is no collusion, when does it end?”

May 16: Trump writes on Twitter: “As President I wanted to share with Russia (at an openly scheduled W.H. meeting) which I have the absolute right to do, facts pertaining.......to terrorism and airline flight safety. Humanitarian reasons, plus I want Russia to greatly step up their fight against ISIS & terrorism.”

May 17: Deputy attorney general Rod Rosenstein appoints former FBI Director Robert Mueller as special counsel to investigate Russia’s interference in the 2016 election and possible collusion with the Trump campaign.

May 18: Trump writes on Twitter: “This is the single greatest witch hunt of a politician in American history!”

He adds later: “With all of the illegal acts that took place in the Clinton campaign & Obama Administration, there was never a special counsel appointed!”

At an afternoon press conference he criticizes the appointment of a special counsel and declares: “there was no collusion.” He also denies telling Comey to drop the investigation into Flynn.

May 31: Trump writes on Twitter: "So now it is reported that the Democrats, who have excoriated Carter Page about Russia, don't want him to testify. He blows away their.... ... ...case against him & now wants to clear his name by showing "the false or misleading testimony by James Comey, John Brennan... Witch Hunt!"

June 8: Former FBI James Comey testifies in front of the Senate Intelligence Committee that he was behind the leaking of memos he wrote during his time as director to the media in order to prompt the appointment of a special counsel. He adds that he was worried the president might lie about their interactions.

June 15: Trump writes on Twitter: "They made up a phony collusion with the Russians story, found zero proof, so now they go for obstruction of justice on the phony story. Nice… You are witnessing the single greatest WITCH HUNT in American political history — led by some very bad and conflicted people!… Why is that Hillary Clintons [sic] family and Dems dealings with Russia are not looked at, but my non-dealings are? … Crooked H destroyed phones w/ hammer, 'bleached' emails, & had husband meet w/AG days before she was cleared- & they talk about obstruction?"

Pence's office confirms that he has retained Richard Cullen to serve as his outside counsel during the Russia probe. Around that time, Cullen meets with Mueller at Pence's request to express Pence's intent to cooperate.

June 22: Trump writes on Twitter: "Former Homeland Security Advisor Jeh Johnson is latest top intelligence official to state there was no grand scheme between Trump & Russia.” Johnson had testified to Congress the day before that Putin directed Russia's interference in the 2016 election but that it did not alter the counting of ballots.

June 23: Trump writes on Twitter: "Just out: The Obama Administration knew far in advance of November 8th about election meddling by Russia. Did nothing about it. WHY?” Johnson had said Obama's response was limited by fear of “taking sides” in the race, particularly after Trump’s warnings that the election would be “rigged.”

June 27: Trump writes on Twitter: "Wow, CNN had to retract big story on 'Russia,' with 3 employees forced to resign. What about all the other phony stories they do? FAKE NEWS!”

Secretary of State Rex Tillerson, who joined Trump for the first meeting, says Trump pressed Putin on election meddling and that the Russian leader repeated his past denials. Trump "pressed him and then felt like, at this point, let’s talk about how do we go forward?” Tillerson said.

July 8: The New York Times breaks the story about Donald Trump Jr.'s June 2016 meeting at Trump Tower with the Russian lawyer. Trump Jr. provided the Times with a statement that the meeting was about an adoption program.

It is later revealed by the Washington Post that Trump himself dictated the statement on the flight home from the G20 meeting.

July 9: Trump opens the day with a series of tweets: “I strongly pressed President Putin twice about Russian meddling in our election. He vehemently denied it. I've already given my opinion…. We negotiated a ceasefire in parts of Syria which will save lives. Now it is time to move forward in working constructively with Russia! … Putin & I discussed forming an impenetrable Cyber Security unit so that election hacking, & many other negative things, will be guarded.... Fake News said 17 intel agencies when actually 4 (had to apologize). Why did Obama do NOTHING when he had info before election?… Sanctions were not discussed at my meeting with President Putin. Nothing will be done until the Ukrainian & Syrian problems are solved!”

The Times reports that Trump Jr. "was promised damaging information about Hillary Clinton before agreeing to meet with a Kremlin-connected Russian lawyer during the 2016 campaign."

Trump Jr. releases a statement about his meeting with June 2016 Veselnitskaya, saying she had arrived offering "information that individuals connected to Russia were funding the Democratic National Committee and supporting Mrs. Clinton." But, he continues: "Her statements were vague, ambiguous and made no sense. No details or supporting information was provided or even offered. It quickly became clear that she had no meaningful information. She then changed subjects and began discussing the adoption of Russian children and mentioned the Magnitsky Act. It became clear to me that this was the true agenda all along and that the claims of potentially helpful information were a pretext for the meeting."

July 10: The Times reports that Trump Jr. was informed in an email that the information he would be provided at the meeting was part of the Russian government's effort to support Trump's candidacy.

Trump Jr.'s lawyer, Alan Futerfas, tells the Times in a statement that "Don Jr. had no knowledge as to what specific information, if any, would be discussed."

July 11: Moments before The Times published portions of Trump Jr.'s emails arranging the meeting, Trump Jr. himself tweets out the emails. In the emails, Goldstone promised "information that would incriminate Hillary and her dealings with Russia and would be very useful to your father." The information, Goldstone noted, "is part of Russia and its government's support for Mr. Trump."

"If it is what you say I love it especially later in the summer," Trump Jr. replied.

That evening, Trump Jr. goes on Sean Hannity's program on Fox News. He tells Hannity the meeting was “such a nothing,” but that "In retrospect, I probably would have done things a little differently.”

Pence's office releases a statement saying Pence is "not focused on stories about the campaign, particularly stories about the time before he joined the ticket."

July 12: Trump's lawyer, Jay Sekulow, tells CNN that neither he nor Trump were "involved in the statement drafting at all" for the July 8 statement which said the meeting had been about adoption.

July 18: The New York Times reveals Trump's and Putin's undisclosed conversation over dinner, for which only a Russian government translator was present. Trump responds on Twitter: "Fake News story of secret dinner with Putin is 'sick.' All G 20 leaders, and spouses, were invited by the Chancellor of Germany. Press knew!" He later added: "The Fake News is becoming more and more dishonest! Even a dinner arranged for top 20 leaders in Germany is made to look sinister!"

July 19: The White House further downplays the July 7 dinner.

"I think that once again the Russia fever has caught up with the media," White House press secretary Sarah Sanders tells reporters. "It was a brief conversation, and certainly not an hour," Sanders later adds, but quips that she was not following Trump around "with a stopwatch."

Trump tells the New York Times he regrets appointing Jeff Sessions as Attorney General and calls Sessions’s recusal in the Russia probe "very unfair to the president." Trump also contends that Comey only shared the famous dossier with him to gain leverage.

July 20: The spokesman for Trump's outside legal team, Mark Corallo, leaves his post after less than two months in the job.

July 21: Marc Kasowitz, Trump's top personal lawyer, is replaced by John Dowd.

The Washington Post reports that "Trump has asked his advisers about his power to pardon aides, family members and even himself in connection with the probe."

July 22: Trump writes on Twitter: "While all agree the U. S. President has the complete power to pardon, why think of that when only crime so far is LEAKS against us.FAKE NEWS.... My son Donald openly gave his e-mails to the media & authorities whereas Crooked Hillary Clinton deleted (& acid washed) her 33,000 e-mails!"

July 23: Trump writes on Twitter: "As the phony Russian Witch Hunt continues, two groups are laughing at this excuse for a lost election taking hold, Democrats and Russians!... It's very sad that Republicans, even some that were carried over the line on my back, do very little to protect their President."

July 24: Trump writes on Twitter: "After 1 year of investigation with Zero evidence being found, Chuck Schumer just stated that 'Democrats should blame ourselves,not Russia.'” ("People didn’t know what we stood for [in 2016], just that we were against Trump,” Schumer had told the Washington Post.)

Kushner testifies behind closed doors before the Senate Intelligence Committee."I did not collude with Russia, nor do I know of anyone else in the campaign who did so,” he tells reporters.

Trump continues to harangue Sessions on Twitter, and also also takes aim at the top Democrat on the House Intelligence Committee, Adam Schiff: "So why aren't the Committees and investigators, and of course our beleaguered A.G., looking into Crooked Hillarys crimes & Russia relations?” Trump tweets, adding: “Sleazy Adam Schiff, the totally biased Congressman looking into ‘Russia,’ spends all of his time on television pushing the Dem loss excuse!"

July 25: Trump writes on Twitter: “Ukrainian efforts to sabotage Trump campaign – ‘quietly working to boost Clinton.’ So where is the investigation A.G. ... Attorney General Jeff Sessions has taken a VERY weak position on Hillary Clinton crimes (where are E-mails & DNC server) & Intel leakers! ... Problem is that the acting head of the FBI & the person in charge of the Hillary investigation, Andrew McCabe, got $700,000 from H for wife!"

The House passes sanctions on Russia by a vote of 419-3. The package was designed as retribution for Russia's meddling in the 2016 election and limits Trump’s ability to unilaterally relax existing sanctions on Moscow.

Around July 25: FBI agents execute an early morning raid on Manafort's home in Virginia, collecting documents, computer files and taking photographs.
