David Bossie and Corey Lewandowski, key advisers to President Trump, said in a joint interview that they witnessed no instances of collusion with Russian entities or operatives during their time serving on his 2016 campaign.

Neither Republican operative served from beginning to end, with Lewandowski exiting his role as campaign manager at the beginning of the general election and Bossie coming on as deputy campaign manager for the final fall push. But the two loyalists, who still speak with Trump regularly, said evidence of campaign officials colluding with Moscow would have leaked if it existed.
