President Donald Trump spent Sunday morning railing against former FBI Director James Comey, whose highly anticipated book will be released Tuesday. In a series of unhinged tweets, the president described Comey, whom he fired last year, as “not smart”; the “worst” FBI chief in history; a “self serving” liar; and a “slimeball.” He even threatened Comey with jail time.

Trump kicked off his tirade by referencing reports that Comey discloses in his book that Hillary Clinton’s lead in 2016 election polling may have influenced Comey’s handling of the FBI’s investigation into Clinton’s email server.

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! — Donald J. Trump (@realDonaldTrump) April 15, 2018

Whatever one thinks of this troubling admission from Comey, it’s worth noting that what Comey actually wrote, according to early reports, is that he may have treated Clinton more harshly because of his assumption that she’d win.

Comey made a similar statement to ABC News in an interview clip released Saturday, saying that his decision to disclose the reopening of the email investigation “must have been” influenced by his belief that Clinton would win.

Trump went on to call “Slippery James Comey” the “WORST FBI Director in history, by far” and insist that the notes Comey took documenting his conversations with Trump are “FAKE.”

Comey throws AG Lynch “under the bus!” Why can’t we all find out what happened on the tarmac in the back of the plane with Wild Bill and Lynch? Was she promised a Supreme Court seat, or AG, in order to lay off Hillary. No golf and grandkids talk (give us all a break)! — Donald J. Trump (@realDonaldTrump) April 15, 2018

I never asked Comey for Personal Loyalty. I hardly even knew this guy. Just another of his many lies. His “memos” are self serving and FAKE! — Donald J. Trump (@realDonaldTrump) April 15, 2018

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! — Donald J. Trump (@realDonaldTrump) April 15, 2018

Trump even threatened Comey with jail time. He also complained that the FBI had not seized the Democratic National Committee’s server during the 2016 campaign.

The big questions in Comey’s badly reviewed book aren’t answered like, how come he gave up Classified Information (jail), why did he lie to Congress (jail), why did the DNC refuse to give Server to the FBI (why didn’t they TAKE it), why the phony memos, McCabe’s $700,000 & more? — Donald J.

Trump also lashed out once again at the law enforcement officials behind last week’s raid on the office, hotel room, and home of Michael Cohen, Trump’s longtime personal attorney. Trump lamented that attorney-client privilege “is now a thing of the past” and that his “many” lawyers are “probably wondering when their offices, and even homes, are going to be raided.”

Attorney Client privilege is now a thing of the past. I have many (too many!) lawyers and they are probably wondering when their offices, and even homes, are going to be raided with everything, including their phones and computers, taken. All lawyers are deflated and concerned! — Donald J. Trump (@realDonaldTrump) April 15, 2018
