(Last updated July 24, 2019.)

U.S. law enforcement agencies and Congress are investigating links between Donald Trump’s presidential campaign and Russia, as part of a broader probe into Moscow’s interference in the 2016 election.

To date, Special Counsel Robert Mueller’s investigation has resulted in five former Trump aides agreeing to work with Mueller’s team under plea deals. Numerous Trump associates had contacts with Russian government officials or business people during the campaign and presidential transition.

As the investigation has unfolded, the Trump team’s stories have changed, recollections have been refreshed and government officials have come forward with new assessments of the intelligence.

This timeline documents everything we know thus far about the investigation into the Trump campaign and Russia. The sources are either verified events, court filings, public statements, or on-the-record media reports.

Late July 2016: A senior Trump campaign official was directed to contact Trump’s longtime friend and associate Roger Stone about any additional WikiLeaks releases, and what additional damaging information the group possessed on the Clinton campaign.

July 25, 2016: The FBI publicly confirmed its investigation into the DNC hack.

Dec. 29, 2016: In the waning days of his presidency, Barack Obama responded to Russia’s interference in the election by expelling 35 Russian diplomats and issuing new sanctions.

Late December 2016: Following Obama’s move against Russia, Flynn asked Kislyak to "refrain from escalating the situation." Kislyak later told Flynn that Russia "had chosen to moderate its response to those sanctions as a result of his request."

Dec. 30, 2016: Putin declined to retaliate against the Obama administration’s sanctions.

Later that day, Trump praised Putin’s decision over Twitter:

Great move on delay (by V. Putin) - I always knew he was very smart! — Donald J. Trump (@realDonaldTrump) December 30, 2016

Jan. 6, 2017: The U.S. intelligence community concluded with "high confidence" that Russia engaged in an influence campaign directed at the election.

Jan. 10, 2017: In his confirmation hearing to become Trump’s attorney general, Sessions said under oath that he did not have contact with Russian officials during the 2016 presidential campaign. In a separate questionnaire submitted a week later, Sessions denied contacting any Russian officials regarding the 2016 election.

Jan. 10, 2017: A dossier compiled by former British intelligence officer Christopher Steele became public. Steele wrote the dossier on behalf of Fusion GPS, a research firm whose work had been funded in part by the Democratic National Committee and Hillary Clinton’s presidential campaign. The document suggested the Kremlin possesses compromising material against Trump and raises the possibility Trump is vulnerable to blackmail.

Jan. 20, 2017: Trump was inaugurated as president.

Late January 2017: Flynn, now Trump’s national security adviser, lied to the FBI, falsely claiming that he never discussed the Obama administration’s Russia sanctions with Kislyak.

Jan. 27, 2017: During a meeting with FBI Director James Comey, Trump said, "I need loyalty, I expect loyalty," according to sworn testimony Comey would later deliver to Congress. Trump has denied this.

Feb. 13, 2017: Flynn resigned after 24 days as national security adviser.

Feb. 14, 2017: Trump asked Comey to drop the investigation into Flynn, according to Comey's sworn testimony. Comey said Trump told him: "I hope you can see your way clear to letting this go, to letting Flynn go. He is a good guy. I hope you can let this go." Trump has denied this.

March 1, 2017: The Washington Post reported that Sessions met with Kislyak twice over the previous year, encounters that Sessions failed to disclose during his confirmation proceedings. Sessions later confirmed these meetings.

March 2, 2017: Sessions recused himself from any "existing or future investigations" related to the 2016 presidential election.

March 20, 2017: Comey publicly confirmed the FBI’s counterintelligence probe includes "investigating the nature of any links between individuals associated with the Trump campaign and the Russian government and whether there was any coordination between the campaign and Russia's efforts."

May 11, 2017: Trump told NBC "this Russia thing" factored into his decision to fire Comey.

May 17, 2017: The Justice Department appointed former FBI Director Robert Mueller as special counsel. Mueller led the investigation into possible ties or coordination between the Trump campaign and Russian officials, as well as other matters that "may arise directly from the investigation."

July 8, 2017: The New York Times reported on the June 9, 2016, meeting at Trump Tower where Trump, Jr., Manafort and Kushner met with a Kremlin-linked Russian lawyer. That story prompted Trump Jr. to issue the following statement to the media:

"It was a short introductory meeting. I asked Jared (Kushner) and Paul (Manafort) to stop by. We primarily discussed a program about the adoption of Russian children that was active and popular with American families years ago and was since ended by the Russian government, but it was not a campaign issue at the time and there was no follow up.

"I was asked to attend the meeting by an acquaintance, but was not told the name of the person I would be meeting with beforehand."

July 9, 2017: The New York Times reported that Trump Jr. arranged the June 9, 2016, Trump Tower meeting after being promised he would receive damaging information about Clinton. For the second consecutive day, Trump Jr. issued a statement to the media about the meeting. (Read a full account of the Trump team’s shifting explanations.)

July 14, 2017: One of the attendees of the Trump Tower meeting, Russian-American Rinat Akhmetshin, a former Soviet soldier with experience in military counterintelligence, said that after the meeting, Russian lawyer Natalia Veselnitskaya left behind documents for the Trump campaign. According to an interview with the Associated Press, Akhmetshin said Veselnitskaya believed the documents detailed "the flow of illicit funds to the Democrats," and she suggested to the campaign that publishing them could help Trump's electoral chances.

Aug. 1, 2017: White House Press Secretary Sarah Huckabee Sanders was asked about a news report that the president had tried to change the narrative around Trump Jr.'s meeting with the Russian lawyer. Sanders said Trump "weighed in" on his son’s statement about the June 9 Trump Tower meeting. Sanders’ statement is inconsistent with previous explanations offered by Trump’s team.

Aug. 2, 2017: Trump signed a law imposing new Russia sanctions in response to Moscow’s interference with the election. Congress largely passed the bill — with veto-proof majorities — in response to Trump’s downplaying of the meddling question and his seeming interest in lifting sanctions against Russia, experts said.

Oct. 5, 2017: Papadopoulos pled guilty to lying to the FBI about his efforts to put the Trump campaign in contact with Moscow. He entered a plea agreement with Mueller.

Oct. 30, 2017: Manafort and Trump campaign associate Rick Gates surrendered to the FBI after being charged with a dozen felonies each, including failing to disclose lobbying activities on behalf of foreign entities, financial crimes and making false statements. They pled not guilty to all charges.

Nov. 2, 2017: Page told the House Intelligence Committee he had notified Sessions about contacts he made with Kremlin officials during his July 2016 Russia. This contradicted Sessions’ previous denials.

Feb. 16, 2018: The special counsel charges 13 Russians and three Russian entities with conspiring to defraud the United States and interfere with the 2016 presidential election.

The Russian government denied involvement.

The special counsel also charged Richard Pinedo with identity fraud. He would later plead guilty.

Feb. 18, 2018: Dutch attorney Alex Van Der Zwaan was indicted for lying to the FBI about interactions with Rick Gates and another associate of Manafort. He would later plead guilty and serve a 30-day sentence before being deported to the Netherlands.

Feb. 22, 2018: A new indictment was filed against Manafort and Gates containing 32 charges, including tax and bank fraud.

Feb. 23, 2018: Gates pled guilty and agreed to work with Mueller’s probe.

Feb. 24, 2018: A new indictment was filed against Manafort alleging he "secretly retained a group of former senior European politicians to take positions favorable to Ukraine, including by lobbying in the United States."

April 9, 2018: The FBI raided the offices of Trump’s longtime lawyer and aide Michael Cohen. The case was referred to the U.S. Attorney’s office in the Southern District of New York.

April 19, 2018: Memos were released of former FBI Director James Comey, providing his contemporaneous written impressions of several one-on-one discussions with Trump.

April 27, 2018: Republican members of the House Intelligence Committee released a final report on the committee’s Russia investigation over Democratic objections. The committee's Republican members found no evidence of collusion between the Trump campaign and Moscow, but concluded that Russia conducted cyberattacks on U.S. political institutions during the 2016 campaign.

The committee’s top Democrat, Adam Schiff of California, criticized GOP members for closing the investigation prematurely, and called their findings superficial and politically motivated. Statements made by Cohen about Trump Tower Moscow, which Cohen later admitted were lies, go largely unchallenged in the report.

May 1, 2018: Trump reacted angrily to a New York Times report containing a list of questions Mueller is said to have sent Trump as part of the special counsel investigation, calling it a "witch hunt."

June 8, 2018: Mueller added an obstruction charge against Manafort and indicted his business partner Konstantin Kilimnik.

July 3, 2018: A Senate panel that independently reviewed the intelligence community’s assessment backed up its findings, concluding that the agencies’ joint assessment was a "sound intelligence product."

July 13, 2018: The special counsel indicted 12 Russian intelligence officers for their role in the hacking of the Democratic National Committee, the Democratic Congressional Campaign Committee and the Clinton campaign, and leaking of emails and documents.

The indictment made reference to an unnamed U.S. person who "was in regular contact with senior members of the presidential campaign of Donald J. Trump," and who communicated during the election with Guccifer 2.0, a front for Russian operatives. Former Trump campaign adviser Stone acknowledged he is "probably" the U.S. person referenced in the indictment.

July 16, 2018: In a joint press conference with Russian President Vladimir Putin, Trump appeared to accept Putin’s denial of Russian election interference. (The following day Trump claimed he misspoke.)

July 21, 2018: In response to a Freedom of Information Act request, the Justice Department released a heavily-redacted version of the warrant application used to obtain a wiretap on former Trump campaign adviser Carter Page starting in October 2016, a month after he parted ways with Trump’s team.

July 27, 2018: Trump denied a CNN report that he knew in advance about the June 9, 2016, Trump Tower meeting. The report was based on unnamed sources who said former Trump attorney Cohen is willing to confirm Trump's foreknowledge of the meeting to the special counsel. In repsonse, Trump tweeted, "I did NOT know of the meeting with my son, Don jr. Sounds to me like someone is trying to make up stories in order to get himself out of an unrelated jam (Taxi cabs maybe?)," an apparent reference to Cohen's role managing taxi companies.

Aug. 1, 2018: Trump called on his attorney general to end the Mueller probe, tweeting: "This is a terrible situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further."

Aug. 5, 2018: Trump tweeted about the June, 9, 2016, meeting at Trump Tower, saying it was "a meeting to get information on an opponent," adding to the series of shifting explanations of the meeting arranged by Donald Trump Jr.

Fake News reporting, a complete fabrication, that I am concerned about the meeting my wonderful son, Donald, had in Trump Tower. This was a meeting to get information on an opponent, totally legal and done all the time in politics - and it went nowhere. I did not know about it! — Donald J. Trump (@realDonaldTrump) August 5, 2018

Aug. 21, 2018: Manafort was convicted of eight of 18 felony counts. A jury found Manafort guilty on five tax fraud charges, one charge of hiding foreign bank accounts and two counts bank fraud. A mistrial was declared for the other 10 charges.

Aug. 21, 2018: Cohen pled guilty in federal court to a series of criminal charges, including a campaign finance law violation that implicated the president. His other convictions concern tax fraud and bank fraud.

Sept. 7, 2018: Papadopoulos was sentenced to 14 days in jail and a year of supervised release after pleading guilty to lying to the FBI.

Sept. 14, 2018: Manafort pled guilty to reduced charges in exchange for an open-ended cooperation agreement that obligates him to "cooperate fully, truthfully, completely, and forthrightly" with the special counsel’s investigation, and possibly other prosecutors.

Oct. 19, 2018: The Justice Department accused Russians with ties to Putin of operating an "information warfare" targeting the U.S. midterm elections.

Nov. 20, 2018: Trump submitted written answers to Mueller’s questions.

Nov. 26, 2018: Papadopoulos reported to prison to serve a two-week sentence.

Nov. 26, 2018: Mueller’s team accused Manafort of breaching his plea agreement, saying he repeatedly lied to federal investigators. The special counsel's office argued in a court filing that "crimes and lies" Manafort committed after the plea deal relieve Mueller’s team from honoring their end of the bargain. Manafort denied the charges.

Nov. 26, 2018: Pundit and conspiracy theorist Jerome Corsi rejected a plea offer from the special counsel. A draft of the plea deal alleges Corsi gave Stone advance notice in August 2016 that WikiLeaks would release damage information on Hillary Clinton. A subsequent indictment of Stone reiterated many of the same allegations.

Nov. 27, 2018: Manafort denied ever meeting with Julian Assange, following a report in The Guardian claiming Trump’s onetime campaign manager held secret talks with the WikiLeaks editor at the Ecuadorian Embassy in London.

"I have never met Julian Assange or anyone connected to him," Manafort said in a statement. "I have never been contacted by anyone connected to Wikileaks, either directly or indirectly. I have never reached out to Assange or Wikileaks on any matter."

Nov. 29, 2018: Cohen pled guilty to to lying to Congress about the Russian-based development proposal Trump Tower Moscow. Cohen admitted he lied when he told lawmakers he had only briefed Trump on the project three times, and that negotiations broke down in January 2016. In fact, talks continued as late as June 2016, after Trump became the Republican Party’s presumptive nominee.

Cohen also concealed his communications with Kremlin officials, as well as the fact he asked Trump to travel to Moscow to further the deal. He said his lies were intended to harmonize with the Trump campaign’s "political messaging."

Nov. 29, 2018: Cohen’s Russian business associate, Felix Sater, said he and Cohen were interested in offering a $50 million penthouse in Trump Tower Moscow to Putin because they believed "it would entice other wealthy buyers to purchase their own."

Rep. Adam Schiff of California, the top Democrat on the House Intelligence Committee said Sater’s comment, if true, shows House investigations should continue to probe "what, if any, financial leverage the Russians may hold over President Trump and the Trump Organization."

Schiff, who is expected to lead the committee when the Democrats take control of the House in January 2019, said the panel intends to call Cohen back to testify again, as do Senate Democrats. The House committee’s Democratic members also plan to send the special counsel all unredacted transcripts of interviews the panel conducted as part of its Russia investigation.

Nov. 30, 2018: Trump responded via Twitter to defend his pursuit of Trump Tower Moscow, describing his business as "very legal and very cool."

"Oh, I get it! I am a very good developer, happily living my life, when I see our Country going in the wrong direction (to put it mildly). Against all odds, I decide to run for President & continue to run my business-very legal & very cool, talked about it on the campaign trail … Lightly looked at doing a building somewhere in Russia. Put up zero money, zero guarantees and didn’t do the project. Witch Hunt!"

Nov. 30, 2018: The special counsel’s office said it may retry Manafort on previous charges that led to hung jury.

Nov. 30, 2018: Lawyers for Cohen requested that he be spared prison, citing Cohen’s cooperation with federal investigations, including the special counsel probe.

Dec. 7, 2018: The special counsel’s office accused Manafort of lying multiple times to investigators, in breach of his federal plea deal.

Dec. 12, 2018: Cohen was sentenced to three years in prison for financial crimes as well as for lying to Congress. He was also ordered to pay $2 million in penalties.

Before the sentence was handed down, Cohen told the courtroom, "It was my own weakness and a blind loyalty to this man (Trump) that led me to choose a path of darkness over light. Time and time again I felt it was my duty to cover up his dirty deeds."

Dec. 13, 2018: Maria Butina, a Russian living in the United States, pled guilty to conspiring to act as an illegal foreign agent. Butina has been accused of trying to infiltrate Republican power circles.

Jan. 8, 2019: Manafort’s lawyers submitted a court filing denying that Manafort breached his plea deal, as the special counsel’s office alleged. The filing inadvertently revealed that Manafort shared 2016 election polling data with his business partner Kilimnik, whom Mueller had previously charged with of obstruction of justice.

Jan. 18, 2019: The special counsel denied a BuzzFeed News report which claimed that Trump directed Cohen to lie to Congress about the Trump Tower Moscow project. In a rare public comment, a spokesman for Mueller said, "BuzzFeed’s description of specific statements to the special counsel’s office, and characterization of documents and testimony obtained by this office, regarding Michael Cohen’s congressional testimony are not accurate."

Jan. 23, 2019: Cohen, in a statement from his lawyer, announced he would not voluntarily testify before the House Oversight Committee in coming weeks, as he had planned. Cohen cited "ongoing threats against his family from President Trump and Mr. (Rudolph) Giuliani" as among the reasons for the reversal. The following day, the Senate Intelligence Committee subpoenaed him; he is slated to testify Feb. 12.

Jan. 24, 2019: The FBI arrested Trump's longtime friend and associate Stone. He was charged with seven felonies, including lying to Congress under oath, witness tampering and obstruction. The indictment lays out a pattern of behavior that gives the strong impression Stone tried to conceal his contacts with WikiLeaks.

Jan. 27, 2019: The Trump administration lifted sanctions on three companies connected to Russian oligarch Oleg Deripaska, over objections from Democratic lawmakers, who were joined by some Republicans. Experts said sanctions relief wasn’t a demonstration of Trump’s coziness with Russian oligarchs, so much as it was his administration’s way of ending the disruption it inflicted on the global metals market when it sanctioned Deripaska’s aluminum company Rusal. (Read our full report.)

March 22, 2019: Mueller concluded his investigation into Russian interference in the 2016 election and related matters. Mueller submitted a confidential report to Attorney General William Barr explaining his "prosecution and declination decisions." Barr told lawmakers who lead congressional judiciary committees in a letter that he would advise them the special counsel's principal conclusions, perhaps as soon as this weekend.

White House press secretary Sarah Sanders said the White House had not received or been briefed on the report. She added that Barr would determine the next steps, adding, "We look forward to the process taking its course."

April 18, 2019: Barr released a redacted version of the special counsel's report spanning about 400 pages. It reaffirmed that Russia favored Trump over Hillary Clinton in the 2016 presidential election, and that the Trump campaign believed it would benefit from Russia’s interference. However, the investigation did not establish coordination or a conspiracy between the Trump campaign and Russia.

The report also outlined "key issues and events" examined as part of the investigation on whether Trump obstructed justice. Mueller did not make a determination on that matter. "The evidence we obtained about the president's actions and intent presents difficult issues that prevent us from conclusively determining that no criminal conduct occurred," Mueller said. "Accordingly, while this report does not conclude that the President committed a crime, it also does not exonerate him."

(Read more about our key takeaways from the report.)

May 29, 2019: Mueller brought the investigation to a formal close in his first public statement about the Russia probe. Mueller recapped Russia’s attempts to interfere in the 2016 presidential election and explained why he could not have brought charges against the president even if he found they were substantiated.

Under long-standing department policy, Mueller said, a president cannot be charged with a federal crime while in office. "That is unconstitutional," Mueller said, adding that even if the charge is kept under seal and hidden from the public, "that, too, is prohibited."

Mueller’s last words emphasized the overarching findings of the nearly two-year probe.

"I will close by reiterating the essential allegation of our indictments, that there were multiple, systematic efforts to interfere in our election," Mueller said. "That allegation deserves the attention of every American."

July 24, 2019: Mueller testified before two House committees, limiting himself to findings published in the special counsel's report. He concluded his opening statement by saying, "Over the course of my career, I’ve seen a number of challenges to our democracy. The Russian government’s effort to interfere in our election is among the most serious. As I said on May 29, this deserves the attention of every American."
