President Trump's eldest son acknowledges that he exchanged direct messages via Twitter with WikiLeaks before and after the release of hacked emails from Clinton campaign chairman John Podesta.
The Senate Judiciary Committee plans to go ahead with a hearing about foreign influence in the United States, albeit without three of the star witnesses it wanted.
