Four lawyers with first-hand knowledge of the Russia probe join anchor Ari Melber for an unusual interview detailing the lengths Mueller’s team went to maintain secrecy and even “intimidate” witnesses. The joint interview includes lawyers for witnesses who cooperated, like Brittany Kaiser and Michael Caputo, and lawyers for ex-Trump aides who pled guilty and flipped on Trump, like George Papadopoulos and Rick Gates, and includes discussion of if Mueller will ultimately prove obstruction or collusion.
