WASHINGTON — Adult film star Stormy Daniels is suing President Donald Trump’s lawyer Michael Cohen for defamation after he called into question her claim that she had a sexual encounter with Trump, according to court documents filed on Monday.

In the filing in federal court in Los Angeles, Daniels’ attorney said “Cohen meant to convey that Ms. Clifford is a liar, someone who should not be trusted, and that her claims about her relationship with Mr. Trump is ‘something (that) isn’t true.’ ”
