Trump calls Comey 'worst FBI director in history,' ahead of book release

President Trump bashed fired FBI Director James Comey several times Sunday on Twitter, calling him the agency’s worst leader “in history,” as the first of several TV interviews in which Comey promotes his tell-all book airs tonight.

“Slippery James Comey, a man who always ends up badly and out of whack (he is not smart!), will go down as the WORST FBI Director in history, by far!” Trump said in one of several tweets Sunday about Comey and his upcoming book, “A Higher Loyalty.”

Trump also tweeted that Comey's mishandling of the Clinton email probe deserves “jail” time and called him a “slimeball.”

“Unbelievably, James Comey states that Polls, where Crooked Hillary was leading, were a factor in the handling (stupidly) of the Clinton Email probe,” Trump tweeted. “In other words, he was making decisions based on the fact that he thought she was going to win, and he wanted a job. Slimeball!
