Anderson Cooper has taped an interview with Stephanie Clifford, the adult film actress known as Stormy Daniels who alleged a sexual relationship with Donald Trump and is now suing the president. The interview will air on the CBS newsmagazine "60 Minutes," where Cooper is a regular contributor. But the exact air date is unknown. A source involved in the taping said it will air "on a future episode." A "60 Minutes" spokesman declined to comment. Cooper interviewed Clifford's lawyer Michael Avenatti on CNN on Wednesday night.
