Washington (CNN) White House press secretary Sarah Sanders faced a battery of questions Wednesday about Stormy Daniels, the porn actress who filed suit against President Donald Trump this week alleging he hadn't signed a nondisclosure agreement that would have prevented her from discussing their alleged sexual affair.

Sanders attempted to stave off the questions by referring them to Trump's outside lawyers. But she did reveal that -- as far as she's aware -- Trump himself did not know his lawyer Michael Cohen made a payment to Daniels in October 2016 to ensure her silence.

"Not that I'm aware of," Sanders said when pressed whether Trump knew about the payment. "Anything beyond what I've already given you, I would refer you to the President's outside counsel."
