This article was updated on April 24, 2018.

Over the course of 2017, as revelations unfolded about the investigation into President’s Trump’s 2016 campaign and any connections to Russian actors, we compiled a lengthy timeline of what we had learned. It was built on an understanding of the state of play and was necessarily refined multiple times as we learned more. Originally created in May, it ended with the appointment of Robert S. Mueller III as special counsel investigating Russian meddling.

Given those limitations, we’ve decided to overhaul it, extending what we know about the Mueller investigation and including newly relevant dates and information. Ideally, this structure will allow for better expansion as needed moving forward.

Many — or probably most — of the items on this timeline will prove to be unimportant or coincidental. For those hoping to get a broad sense of the investigation that’s underway, though, we hope it’s informative.

Use the tool below to highlight particular individuals or threads of the investigation.

Before the election

January 2013
Energy industry consultant Carter Page meets a man named Victor Podobnyy at a conference in New York and begins sharing with him “basic immaterial information and publicly available research documents” (in Page’s words). Podobnyy was an officer with Russia’s foreign intelligence service and is later charged with being an agent of the Russian government.

March 2013
The FBI interviews lobbyist and political consultant Paul Manafort. It’s not clear what the interview pertains to.

June 2013
The FBI interviews Page after Podobnyy is recorded by U.S. intelligence officials identifying Page as a possible target for recruitment. “It’s obvious that he wants to earn lots of money,” Podobnyy says of Page.

Aug. 25, 2013
In a letter sent to a publisher making the case for his expertise on Russia, Page writes, “Over the past half year, I have had the privilege to serve as an informal advisor to the staff of the Kremlin in preparation for their Presidency of the G-20 Summit next month, where energy issues will be a prominent point on the agenda.”

Sept. 4, 2013
James B. Comey becomes director of the FBI, succeeding Robert S. Mueller III.

Nov. 8, 2013
Trump arrives in Moscow for the Miss Universe pageant, at this point part of the Trump Organization. The event’s location was secured thanks to licensing fees of nearly $20 million paid by a Moscow real estate development firm called the Crocus Group. Its president is a man named Aras Agalarov. Agalarov’s son, Emin, is a vice president of Crocus Group and a pop singer. Trump’s itinerary that day included a trip to Nobu with Emin Agalarov and, that evening, a birthday party for Aras.

According to various reports, Trump spends the night in a suite at the Moscow Ritz-Carlton. Former British intelligence officer Christopher Steele, based on information apparently from a Belarusan American businessman named Sergei Millian, later reports that Trump’s stay at the hotel included an encounter with Russian sex workers — an encounter documented by Russian intelligence. Trump’s long-time aide Keith Schiller testified that on the morning of Trump’s arrival, someone offered to send several prostitutes to Trump’s room, an offer that Schiller says he declined.

Nov. 9, 2013
The pageant is held. Trump departs Moscow before dawn the next day, according to flight records.

September 2015
An associate of Trump’s named Felix Sater reaches out to the Trump Organization about a proposed development project in Moscow. It is to be financed by Russia’s government-owned bank Vnesheconombank, which was being sanctioned by the U.S. government. Trump at some point signs a letter of intent to move forward with the project.

Autumn 2015
The conservative website the Washington Free Beacon hires a firm called Fusion GPS to conduct research on several Republican presidential candidates, including Trump.

Late 2015
British intelligence agencies detect suspicious interactions between Russia and Trump aides that they pass on to U.S. intelligence agencies.

Mid-January 2016
Cohen emails Putin’s personal spokesman seeking help in advancing the proposed development in Moscow. “As this project is too important, I am hereby requesting your assistance.

I thank you in advance for your assistance and look forward to hearing from you soon,” he writes.

Jan. 29, 2016
Goldstone emails Donald Trump Jr. to pitch the Trump team on setting up a page on Russian social media site Vkontakte. Trump Jr. passes it on to Dan Scavino, the person in charge of Trump’s social media. “Please feel free to send me whatever you have,” Scavino replies.

Feb. 1, 2016
Republican primary voting begins in Iowa.

March 2016

March 19, 2016
Hillary Clinton campaign chairman John Podesta is sent an email that encourages him to change his email password, probably precipitating the hack of his account.

During an interview with The Washington Post, Trump lists Page as part of his foreign-policy team. Page had been recommended by a son-in-law of President Richard Nixon, New York Republican Party Chairman Ed Cox. Trump also mentions Papadopoulos.

At some point during the spring, long-time Trump confidante Roger Stone tells an associate that he had spoken with Assange and learned about emails WikiLeaks possessed that would be problematic for Democrats, including Podesta.

March 28, 2016
Political veteran Manafort is hired to help the Trump campaign manage the delegate process for the Republican National Convention. He is recommended by Stone. Before joining the campaign, Manafort lobbied on behalf of Oleg Deripaska, a Putin ally. That business relationship followed a memo from Manafort in which he offered a plan that could “greatly benefit the Putin Government.” His business relationship with Deripaska ended in 2009. Manafort also worked on behalf of the Russia-friendly Party of Regions in Ukraine, helping guide the party’s leader, Viktor Yanukovych, to the country’s presidency. Yanukovych was later ousted.

March 31, 2016
Trump’s foreign-policy team meets. Included in the meeting are Papadopoulos, Trump and then-Alabama Sen. Jeff Sessions (R). Papadopoulos says he can facilitate a meeting between Trump and Putin based on his interactions with Mifsud, the professor. Sessions says it shouldn’t happen, though Papadopoulos later reportedly tells Mueller that Trump encouraged the meeting.

April 2016
Hackers believed to be linked to Russia’s Main Intelligence Directorate (GRU) also gain access to the DNC network. The Internet Research Agency begins buying ads on social media aimed at promoting Trump’s candidacy and undermining Hillary Clinton.

April 11, 2016
Manafort emails longtime aide Konstantin Kilimnik (who himself may have ties to Russian intelligence) to ensure the oligarch Deripaska’s “operation” has seen his media coverage, presumably about the Trump campaign. “How do we use to get whole?” he asks.

Papadopoulos is introduced via email to someone who has contacts at Russia’s Ministry of Foreign Affairs. Papadopoulos and the contact begin communicating regularly to try to set up a meeting between Trump and Putin.

April 26, 2016
Papadopoulos is told by Mifsud that the Russians have “dirt” on Clinton. “They have thousands of emails,” he is told.

April 27, 2016
Jared Kushner, Trump’s son-in-law, meets Kislyak at a reception at the Mayflower Hotel in Washington before a foreign-policy speech given by Trump. Sessions may have spoken with Kislyak, as well.

The same day, Papadopoulos emails senior campaign adviser Stephen Miller to say he had “some interesting messages coming in from Moscow about a trip when the time is right.”

May 2016
During a night of drinking in London, Papadopoulos tells Australian High Commissioner to Great Britain Alexander Downer that he is aware that Russia has dirt on Clinton.

During this month, two different people who support Trump email the campaign to set up a meeting between a Trump staffer and the banker Torshin. The emails, sent to adviser Rick Dearborn, are titled “Kremlin Connection” and “Russian backdoor overture and dinner invite.” Kushner rejects the latter overture.

May 20 or 21, 2016
Torshin and Trump Jr. meet at a dinner related to the National Rifle Association convention in Louisville.

In an effort to keep the proposed Moscow Trump Tower deal moving forward, Felix Sater encourages Michael Cohen to join him at the St. Petersburg International Economic Forum. An invitation is reportedly arranged by a former Russian intelligence officer. Neither attends and the project is tabled.

June 3, 2016
Goldstone emails Trump Jr.:

“The Crown prosecutor of Russia met with [Emin Agalarov’s] father Aras this morning and in their meeting offered to provide the Trump campaign with some official documents and information that would incriminate Hillary and her dealings with Russia and would be very useful to your father,” Goldstone wrote. “This is obviously very high level and sensitive information but is part of Russia and it’s government’s support for Mr. Trump — helped along by Aras and Emin.”

“Seems we have some time and if it’s what you say I love it especially later in the summer,” Trump Jr. replied.

June 6, 2016
Goldstone appears to connect Emin Agalarov and Trump Jr. by phone.

June 7, 2016
Goldstone and Trump Jr. finalize “a meeting with you and The Russian government attorney.”

Trump formally clinches the nomination later in the day. During a speech that evening, Trump says he is “going to give a major speech on probably Monday of next week, and we’re going to be discussing all of the things that have taken place with the Clintons. I think you’re going to find it very informative and very, very interesting.”

June 9, 2016
Trump Jr., Manafort and Kushner meet at Trump Tower with a Kremlin-connected attorney named Natalia Veselnitskaya. Veselnitskaya’s efforts to reverse a law passed in 2012 sanctioning Russians suspected of human rights violations at some point drew the attention of the FBI. The meeting was not initially reported to the government by Kushner as required when he took a position with the administration. After the meeting was originally reported, Trump, Jr. admitted that the pretext for the conversation was that he believed Veselnitskaya to have information incriminating Hillary Clinton.

The meeting also included a lobbyist named Rinat Akhmetshin, who also has links to Russian intelligence.

June 20, 2016
Steele, working for Fusion GPS, compiles the first of the 17 reports that will become part of his dossier of information alleging contacts between the Trump campaign and Russian actors.

The compromising information on Trump includes the alleged events at the hotel in Moscow in 2013.

June 29, 2016
Goldstone reaches out to Scavino again about Vkontakte.

“I’m following up on an email [from] a while back of something I had mentioned to Don and Paul Manafort during a meeting recently,” he wrote in an email, cc-ing Sidorkov. “At the time, Paul had said he would welcome it …”

Page travels to Moscow to give a lecture.

The same day, Manafort contacts Kilimnik again to invite Deripaska to get a private briefing on the campaign.

July 8, 2016
Page sends a memo to campaign staff with an overview of his travel. It reads, in part, “Russian Deputy Prime Minister and [New Economic School] Board Member Arkadiy Dvorkovich also spoke before the event.

July 19, 2016
Steele files a report in which he alleges that Page‘s trip to Moscow included meetings with the chief executive of the energy firm Rosneft and Kremlin official Igor Diveykin, the latter of whom mentioned the possession of compromising material on Clinton.

Oct. 28, 2016
FBI Director Comey sends a letter to Congress announcing the discovery of new emails related to an investigation into Clinton’s use of a private server while she was secretary of state.

Oct. 30, 2016
Then-Senate Minority Leader Harry M. Reid sends a public letter to Comey alleging that the FBI “possess[ed] explosive information about close ties and coordination between Donald Trump, his top advisors, and the Russian government.” This is apparently a reference to the Steele dossier.

Nov. 28, 2016
In an interview with Time magazine, Trump denies interference from Russia. “I don’t believe they interfered,” he said. “That became a laughing point, not a talking point, a laughing point. Any time I do something, they say, ‘Oh, Russia interfered.’”

Nov. 30, 2016
The Justice Department informs Flynn that he is under investigation for his unreported lobbying on behalf of Turkey.

Dec. 1, 2016
Flynn and Kushner meet with Kislyak at Trump Tower. Kushner allegedly proposes setting up a back-channel of communication between the administration and Putin, perhaps going so far as to use secure communications systems at the Russian Embassy.

Individuals close to Kushner indicate the only focus of the back-channel would be Syria.

Dec. 8, 2016
Page is back in Moscow to meet with “business leaders and thought leaders.”

Jan. 9, 2017
The Trump transition team announces that Kushner will join the administration as an unpaid senior adviser.

Jan. 10, 2017

Departing national security adviser Susan E. Rice asks Flynn to approve an operation in Syria in alliance with Kurdish forces that would extend into Trump’s presidency. The alliance with the Kurds is opposed by the Turkish government. Flynn declines.

Jan. 11, 2017
Erik Prince, brother of Education Secretary nominee Betsy DeVos and founder of Blackwater, meets with a Russian official in the Seychelles. Investigators believe that the meeting may have been part of a continued effort to set up a back-channel with the Russians. The meeting was facilitated by Nader reportedly at the behest of the UAE.

Jan. 26, 2017
Yates meets with McGahn, now White House counsel, and explains that public statements from the vice president contradict what was known about Flynn, making it possible that the Russians could compromise the national security adviser by threatening to leak that information. McGahn “immediately” briefs Trump on the conversation.

A Trump lawyer later acknowledges that Trump believed that Flynn had lied to the FBI by the end of this month.

Jan. 27, 2017
Yates returns to the White House to meet with McGahn again at his request. McGahn asks to review the evidence against Flynn.

Trump calls Comey at noon to see whether he could come to the White House for dinner. During that meeting, Trump allegedly asks Comey to pledge his loyalty to the president. Instead, Comey offers only his honesty. Comey again tells Trump that the president isn’t under investigation. Trump tells Comey that Flynn “has serious judgment issues.” He also again denies the allegations involving the Moscow Ritz-Carlton and denies he even spent the night in Moscow.
