There is a web of connectionsbetween the Trump campaign, the anti-secrecy website WikiLeaks and the public disclosures it injected into the presidential campaign. Federal investigators are examining some of these relationships and whether any of them were part of an effort to coordinate with Russia's election-meddling efforts.
On Monday, it was revealed that Donald Trump Jr. exchanged some private messages on Twitter with WikiLeaks during the 2016 presidential campaign. The news was first reported by The Atlantic and later confirmed by Trump Jr., who posted screenshots of the messages.
A source familiar with the matter told CNN that Congress has known about these messages for a while and they came up during Trump Jr.'s closed-door testimony in September.
The messages show that WikiLeaks reached out fairly often to Trump Jr., who is only known to have replied on two occasions. Trump Jr.'s final response to WikiLeaks was in October 2016, though the WikiLeaks account continued its outreach until July 2017, according to the messages he released.
That being said, nothing happens in a vacuum, and while these messages were exchanged, WikiLeaks was busy releasing hacked materials. And all the while, Russian President Vladimir Putin was directing an operation to interfere in the US election, according to the US intelligence community.
Here is a timeline with what we know about Trump Jr.'s exchanges with WikiLeaks, the role WikiLeaks played, relevant public statements from the Trump campaign, and much more.
July 2015 -- Russian hackers breach DNC systems
Hackers working for Russian intelligence services "gained access to" the Democratic National Committee's computer networks as part of the Kremlin's campaign to interfere in the 2016 presidential race, according to the US intelligence community assessment that was published after the election.
March 2016 -- Another group of Russian hackers breach DNC systems
Another group of Russian hackers -- separate from the group that hacked the DNC in 2015 -- breached the DNC's computer systems, according to a US intelligence report published after the election. The US intelligence community says Russian intelligence related stolen materials from the DNC to WikiLeaks for public release.
CNN reported this year that Russia gave WikiLeaks the emails through an intermediary.
March 19, 2016 -- Russian hackers gain access to Podesta's emails
Russian hackers gained access to Clinton campaign chairman John Podesta's personal Gmail account by sending a phishing email. The US intelligence community determined in early 2017 that Russian intelligence later gave WikiLeaks hacked emails from Democratic "political figures," an oblique reference to Podesta. CNN reported this year that Russia gave WikiLeaks the emails through an intermediary.

Cambridge Analytica, a data analytics firm, started working for Trump over the summer of 2016. Some members of Cambridge Analytica staff were incorporated in the Trump campaign's data operation team. Alexander Nix, the chief executive of data firm Cambridge Analytica, emailed WikiLeaks founder Julian Assange seeking access to emails from Clinton's private server so he could turn them into a searchable database for the campaign or a pro-Trump political action committee. There is no evidence that Clinton's deleted emails were ever hacked or that WikiLeaks ever had possession of them.

Donald Trump Jr., his brother-in-law Jared Kushner, and Trump's then-campaign chairman Paul Manafort attended a private meeting at Trump Tower with a Russian lawyer and others. The meeting was arranged after Trump Jr. was promised damaging information on Hillary Clinton.
June 15, 2016 -- DNC claims it was hacked by Russian intelligence
The DNC and CrowdStrike, a cybersecurity firm it hired to investigate the breaches, revealed publicly for the first time that its servers were penetrated. CrowdStrike said it "identified two sophisticated adversaries on the network" that were associated with Russian intelligence services.
Trump dismissed the notion that Russia was behind the hacks, saying "we believe it was the DNC that did the 'hacking' as a way to distract from the many issues facing their deeply flawed candidate and failed party leader. Too bad the DNC doesn't hack Hillary Clinton's 33,000 missing emails."
July 22, 2016 -- WikiLeaks releases about 20,000 hacked DNC emails

July 27, 2016 -- Trump publicly asks Russia to hack Clinton's deleted emails
At a news conference, Trump publicly called on the Russian government to hack Clinton's private email server and reveal the deleted emails. Trump's campaign later said his comment was a joke.
"If it is Russia -- which it's probably not, nobody knows who it is -- but if it is Russia, it's really bad for a different reason, because it shows how little respect they have for our country, when they would hack into a major party and get everything," Trump said. "But it would be interesting to see -- I will tell you this -- 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. Let's see if that happens. That'll be next."
August 8, 2016 -- Roger Stone says he was in touch with Assange
During a speech in Florida, former Trump campaign adviser Roger Stone claimed to be in touch with Assange and predicted upcoming WikiLeaks releases: "I actually have communicated with Assange.

He later clarified that while he was in contact with Assange, it came through an intermediary.
August 14-17, 2016 -- Stone exchanges messages with Russian hackers
Stone exchanged direct Twitter messages with Guccifer 2.0, a self-proclaimed hacker who published stolen materials from the DNC earlier in the summer. (These DNC releases were separate from the DNC emails published by WikiLeaks.) The Twitter messages were about the contents of some of the stolen DNC materials that Guccifer posted online earlier that summer. Stone denies any wrongdoing or collusion.
Months after these Twitter messages, the US intelligence community announced that Guccifer 2.0 was actually run by Russian intelligence operatives as part of the Kremlin's effort to meddle in the election.

November 8, 2016 -- WikiLeaks tells Trump Jr. that Trump should not concede if he loses
WikiLeaks tells Don Jr. that Trump should contest the election and claim that it was rigged if he does not win. This messaging is consistent with the Russian government's posturing around the time of the election, according to the report released by the US intelligence community in January 2017. The report said: "Before the election, Russian diplomats had publicly denounced the US electoral process and were prepared to publicly call into question the validity of the results. Pro-Kremlin bloggers had prepared a Twitter campaign, #DemocracyRIP, on election night in anticipation of Secretary Clinton's victory, judging from their social media activity."

She also told the AP: "It never happened. There was no communication between the campaign and any foreign entity during the campaign."

Kellyanne Conway denies any contact between the Trump campaign and Russia in an interview with CBS News' John Dickerson.
DICKERSON: All right. We are not going to get any insight into the president-elect's thinking here, but let me try this. Did anyone involved in the Trump campaign have any contact with Russians trying to meddle with the election?
CONWAY: Absolutely not. And I discussed that with the president-elect just last night. Those conversations never happened. I hear people saying it like it's a fact on television. That is just not only inaccurate and false, but it's dangerous.
