Trump: 'Bothersome' that special counsel Robert Mueller is 'very, very good friends with Comey'

Mueller is investigating Russia's interference in the 2016 election.

Trump in a Fox News interview that aired Friday was asked whether he thinks Mueller should recuse himself from the Russia probe he is leading.

"Well, he is very, very good friends with Comey, which is very bothersome," Trump said. "We're going to have to see."

Trump asserted in the interview, "There's been no collusion, no obstruction and virtually everybody agrees to that."

Comey succeeded Mueller, who was FBI director from 2001 to 2013 under both Republican and Democratic presidents and has been a registered Republican through most of his career.

The attorneys hired onto Mueller's special counsel team were brought on using the same standards that the Department of Justice uses to hire career attorneys.
