Michael Cohen, President Donald Trump's personal lawyer, will invoke his Fifth Amendment rights against self-incrimination in a California defamation suit by Stormy Daniels, according to a court filing late Wednesday. In the filing, Cohen said he's pleading the Fifth due to the ongoing criminal investigation against him by federal authorities. Daniels, the adult film actress who claims Cohen paid her $130,000 in hush money to keep quiet about a 2006 affair she had with Trump, sued him earlier this month after Cohen called her a liar.
