In my opinion, I think President Trump should have fired Jeff Sessions when he recused himself from the Russiagate investigation.
In the audio clip provided by the New York Times, President Trump makes himself quite clear on Jeff Sessions.
Originally from NYT:
In a remarkable public break with one of his earliest political supporters, Mr. Trump complained that Mr. Sessions’s decision ultimately led to the appointment of a special counsel that should not have happened. “Sessions should have never recused himself, and if he was going to recuse himself, he should have told me before he took the job and I would have picked somebody else,” Mr. Trump said.
I agree with President Trump wholeheartedly.
