Bannon said that Rosenstein “either…is going to take the direct order of the President of the United States or I think Rosenstein will be fired.”

Bannon also said that the president should give evidence in writing — but not in person — to special counsel Robert Mueller. Bannon praised Mueller as an “honorable guy.”

The comments, which come amid increasing pressure on Rosenstein from Trump and his allies, were made in a wide-ranging interview with the BBC’s “Newsnight,” which was conducted on Tuesday in Prague.
