As President Donald Trump returns to the U.S. from his Asian tour as he spoke with several nations about topics like trade, he is coming back to many pressing issues, one of which involves his oldest son.

On Monday night, Donald Trump Jr. confirmed that he shared messages with WikiLeaks, the organization which publishes hacked communications online.

The president’s oldest son tweeted what he alleged are his entire chain of messages with WikiLeaks: three responses, though WikiLeaks sent many messages that went unanswered.



WikiLeaks also asked Trump Jr. to contest election results and disseminate their work.

Long-form, online magazine The Atlantic initially broke the story Monday, reporting on the "secret correspondence" between Trump Jr. and Wikileaks.

WikiLeaks tweeted a private message to Trump Jr., sharing that an anti-Trump site was about to launch and offering its password.

"So here was Donald Trump Jr. actively engaged with a known Russian agent. I want him to be subpoenaed to testify in public about all his communications," said U.S. Richard Blumenthal, (D) Connecticut.

"The fact of the matter was this was clearly one of the outlets the Russians were using for publication, the campaign knew it," said U.S. Rep. Adam Schiff, (D) Ranking Member, Intelligence Committee. "They were more than willing to work with them, more than willing to trumpet the Wikileaks disclosures and you had a candidate out there on a daily basis, bragging about how wonderful Wikileaks was and the latest Wikileaks disclosures."

WikiLeaks publishes emails stolen from a variety of sources, from the CIA to French President Emmanuel Macron.

The organization, which has claimed it has no ties to Russia, also shared scores of hacked emails from the Clinton camp and Democratic National Committee.

In an intelligence assessment released last January, the NSA, CIA and FBI concluded that Russian military intelligence provided hacked information from the DNC and “senior Democratic officials” to WikiLeaks. WikiLeaks has denied that Russia was the source of emails it released, including those from Clinton’s campaign chairman, John Podesta.

However, the CIA said that director, Mike Pompeo, stands by its report that Russia "ran an influence campaign, aimed at helping the president win the White House in 2016."

In the past, Pompeo denounced WikiLeaks, spearheaded by exiled man Julian Assange, calling them a “hostile intelligence service.”

The investigation into who was doing what — and for whom — continues in D.C.
