Michael Cohen’s lawyer says that his client plans on revealing some “chilling” details about what it was like to work in the Trump Organisation boardroom for nearly a decade, before Donald Trump became president.

“He needs to tell his personal story to the American people,” Lanny Davis, Cohen’s attorney, told ABC News.

He continued: “And when he does, you’re going to hear personal, front-line experiences of memories, and incidents, and conduct, and comments that Donald Trump said over that 10-year time period behind closed doors that, to me when I first heard Michael tell me all this, even as much as I knew about Trump that was negative, was chilling.”

During his interview, Mr Davis said that Cohen will discuss Mr Trump’s behaviour as a private businessman.

“He treats people badly,” Mr Davis said of Mr Trump. “He has no moral character in defrauding people in his businesses, and going bankrupt, and taking cash out, and putting people out of work. He lacks the moral compass that we expect in our presidents.”

Cohen has indicated that he will testify before closed sessions of the Senate and House intelligence committees, and that he will also testify in public before the House Oversight and Government Reform Committee.

He is expected to report to prison on 6 March, after pleading guilty to six felonies in August. Those charges were related to his personal business dealings, and included making false statements to a bank, tax evasion, and felony campaign finance violations.
