Michael Cohen the convicted liar is Alvin Bragg's star witness in the prosecution of Donald Trump. The testimony of Michael Cohen's personal attorney, Robert Costella, before Bragg's grand jury has totally destroyed Cohen's credibility as a witness. Bragg knows they don't have a legitimate case against Trump, he just wants to indict Trump so that he, the Democrats, and the news media can show Donald Trump in handcuffs just as they did to Roger Stone and Paul Manafort.
