Michael Cohen, President Donald Trump's former attorney, seems to have cooked up what one legal expert described as a "fascinating social experiment."

Cohen appeared on CNN's Thursday broadcast of "The Lead" with Jake Tapper, where the two discussed an upcoming interview that Cohen conducted with Trump. The interview stunned some political analysts because of Cohen's involvement in getting Trump convicted on 34 felony counts in New York for falsifying business records related to a hush money payment Trump sent to a porn star ahead of the 2016 election.

Michael Cohen, the former fixer who once vowed to "take a bullet" for Donald Trump before helping to convict him, has done the once-unthinkable: he sat down and interviewed the president.

Cohen spoke with Trump by phone for roughly 40 minutes Thursday morning, with portions set to air that evening on his 77WABC radio show, "When You Know, You Know," and the rest on Sunday. It is, Cohen said, "the first public conversation between the president and myself in eight years."

The Department of Justice has discussed using former attorney Michael Cohen – who has seemingly come crawling back – as a witness to build new criminal cases against President Donald Trump's legal adversaries, according to a new report.

Zeteo's Asawin Suebsaeng, who has a personal history with Cohen, the president's longtime personal attorney and fixer, reported that Trump administration officials are hoping to leverage his testimony to bring criminal prosecutions against New York Attorney General Letitia James and Manhattan District Attorney Alvin Bragg – both of whom successfully battled Trump in court.
