Michael Cohen's Grand Jury Testimony Threatens Trump's Legal Defense.

Michael Cohen, former lawyer and fixer for Donald Trump, is set to testify again against his former boss in the porn star hush money case being investigated by the Manhattan district attorney in New York. Cohen has testified at least 20 times about alleged illegalities by Trump, including whether his former boss told Cohen to provide $130,000 to pornographic film actress Stormy Daniels in the last days of the 2016 campaign. The testimony from Cohen, who has already been convicted and served prison time, could fuel the first charges in history against a former president.
