Trump campaign foreign policy aide George Papadopoulos detailed in filings associated with his guilty plea agreement how Russians in April 2016 were offering the campaign emails damaging to Clinton. Emails between the president’s son, Donald Trump Jr., and a former business partner show that the younger Trump was eager to see the supposedly incriminating information in advance of a Trump Tower meeting. Trump Jr. later traded messages with WikiLeaks founder Julian Assange about his father’s exploitation of emails stolen from Clinton campaign chair John Podesta. On Oct. 12, 2016, after Assange suggested that the GOP nominee help publicize the latest batch of stolen emails, Trump himself sent a tweet praising WikiLeaks just 15 minutes later.
