The group published leaks of Clinton campaign emails during the election.
In July 2016, the organization released thousands of emails that had been stolen from the Democratic National Committee by a cyberhack that USA intelligence officials concluded was orchestrated by the Russian government. Four days later, WikiLeaks began publishing emails stolen from Clinton's campaign director John Podesta. He also asked the site about a rumor about an upcoming leak.
July 2016: Trump becomes the Republican nominee for president at the party's convention in Cleveland, Ohio. The copies of the messages released by Trump Jr. don't contain a response.
It gave three reasons why it claimed such a disclosure would benefit both the Trump campaign and WikiLeaks.
In a statement, Trump Jr.'s lawyer said thousands of documents had been turned over to the committees.
Alan Futerfas, Trump Jr.'s attorney, said his client's exchanges with WikiLeaks were innocuous. A person familiar with that meeting said the private Twitter messages were discussed.
Trump exchanged a handful of messages with Wikileaks via social media site Twitter between September and October of previous year and copies of the correspondence were then leaked to Atlantic magazine.
Trump Jr. quickly answered: "Already did that earlier today. It's wonderful what she can get away with".

Senator Smith said he was hopeful the Yes vote would prevail, but even if Australians voted No he would still introduce the Bill to the Senate this week.
Trump Jr. has also come under scrutiny for a meeting he had last summer with a Russian lawyer who promised damaging information about Clinton. Additionally, there were several occasions during the course of the campaign where a Wikileaks communication with the younger Trump would advise him that information would be released and we would see a "tease" from Trump Sr. or others about "big information" that was going to be released about Clinton. Two days later, Trump jnr tweeted the link to his followers, writing, "For those who have the time to read about all the corruption and hypocrisy all the @wikileaks emails are right here: http://wlsearch.tk/". Trump Jr. tweeted that link two days later, on October 14, 2016, The Atlantic noted.
As BuzzFeed's Chris Geidner notes, on October 14 2016, Pence appeared on Fox and Friends to dispel and questions about the Trump campaign's communications with WikiLeaks, an organization which Trump's own CIA Director Mike Pompeo has labeled a "hostile intelligence service".
They show the organisation made a series of requests: from asking for comments and suggesting President Trump retweet a link, to suggesting Mr Trump should not concede if he lost the election. Like this one in December to make Assange the Australian ambassador to the United States.
One of the huge email leaks came hours after the Access Hollywood tape in which Trump talked about sexually assaulting women was made public, diverting attention from a Trump scandal to a Clinton scandal. Trump Jr. then released them himself.
Vice President Mike Pence said, via his spokesman, that he was "never aware of anyone associated with the campaign being in contact with Wikileaks".
Glaser has continued to follow the story as well, publishing a Medium blog post earlier this week - just before The Atlantic's piece - about Robert Mueller's probe of the relationship between Russian Federation and Trump.
The newly revealed exchanges provide additional information about the role played by Trump Jr.in 2016. California Rep. Adam Schiff, the top Democrat on the House intelligence committee, says it "demonstrates once again a willingness by the highest levels of the Trump campaign to accept foreign assistance".
The leaked Twitter exchanges are likely to increase calls for Mt Trump Jr.to testify publicly in front of the various committees.
