Trump ally Robert Costello said on Monday that he had attacked the credibility of former Trump attorney Michael Cohen while appearing before a Manhattan grand jury investigating the 2016 hush-money payment to adult film star Stormy Daniels.
Costello, himself an attorney who formerly represented Cohen and Rudy Giuliani and was accused of dangling a pardon to Cohen during the Mueller investigation, appeared before the grand jury at Trump's request and said he testified that Cohen is a "serial liar."
