Michael Cohen, the former fixer for President Trump, has been using his time behind bars to write a tell-all book about his time as the president’s personal lawyer and plans on publishing it before the election in November, according to a report.

Actor and comedian Tom Arnold told the Daily Beast that he’s been in regular contact with Cohen, who told him the book would take no prisoners.

“It’s like ‘Jaws’ — you don’t see Jaws [the shark] very much, but you hear the music, and for Trump, he knows Michael is coming and Trump better hear the ‘Jaws’ music,” Arnold told the media outlet.

“He told me he’s been writing a book and he’s pissed. He told me he is going to spill the beans. What has he got to lose now?” Arnold said.

Cohen was released from the upstate Otisville federal prison last week over concerns about coronavirus and will be quarantined for 14 days before being reunited with his family.

He will serve the remainder of his three-year sentence at home.

The 53-year-old disbarred lawyer was sentenced to federal prison for lying to Congress and violating campaign finance laws because of hush-money payments made to a former porn star and Playboy playmate who claimed they had affairs with Trump before he became president.

Cohen, who had a falling out with Trump and testified to Congress, has wanted to tell his side of the story.

“He has been using his time wisely inside to write a book and no one should be surprised as he’s always talked about writing a book,” someone close to Cohen told the Daily Beast.

“Michael’s stories about Trump are incredible. He has saved a lot of them for when the time is right and the time is now right. Michael spent a long time with Trump — he is going to go into everything and he’s not going to hold anything back. He has paid his dues and he’s pissed he had to go to jail for this,” the person said.

Cohen’s attorney, Roger Bennet Adler, declined to comment to the Daily Beast.
