President Trump unleashed on James Comey Sunday morning in a ferocious tweetstorm and even threatened the former FBI chief with jail for leaking classified information.

James Comey fired off a tweet a few hours later and Trump supporters on Twitter torched him.

Crooked cop Comey is set to embark on a book tour to peddle his fictional memoir “A Higher Loyalty.”

Excerpts of the book have made their rounds ahead of the April 17 release date.

Comey personally attacked President Trump by trashing his marriage to First Lady Melania and poked fun at his appearance.

The disgraced former FBI Director had the nerve to say Trump “is unethical, and untethered to truth and institutional values.”

Sunday morning Trump hit Comey hard and even threatened him with jail.

Trump tweeted: “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?”
