Asked in an interview with the New York Post why he believes Rosenstein belongs behind bars, Trump replied, “He should have never picked a special counsel.”

Trump declined to answer a follow-up question on whether he intends to fire Rosenstein.

Earlier Wednesday, Trump railed against the Mueller probe and retweeted several tweets in the morning from the Trump Train, a fan account.

One of them showed 10 current and former government officials behind bars and asked: “Now that Russia collusion is a proven lie, when do the trials for treason begin?”
