Former Trump 2016 campaign deputy chair Rick Gates was once widely portrayed as the key Mueller witness who would expose Trump-Russia collusion. Gates' testimony ended up seriously undermining the collusion conspiracy theory, but that has done little to undo the media narrative.

Gates joins Pushback to debunk several key Russiagate conspiracy theories: that Konstantin Kilimnik is a Russian spy; that Paul Manafort served Russian interests in Ukraine; and that Roger Stone gave the Trump campaign advance notice on Wikileaks' release of stolen Democratic Party emails.

Guest: Rick Gates. Former Trump 2016 deputy campaign chairman, cooperating witness in the Mueller investigation, and author of "Wicked Game: An Insider's Story on How Trump Won, Mueller Failed, and America Lost."
