In an excerpt shown Saturday, Comey says his belief that Hillary Clinton would win the 2016 presidential election was a factor in his decision to disclose the investigation into her emails.

In his tweet, Trump says: "Unbelievably, James Comey states that Polls, where Crooked Hillary was leading, were a factor in the handling (stupidly) of the Clinton Email probe. 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!"
