Stephanie Clifford, also known as Stormy Daniels, is an adult film star who appeared in and directed scores of films. It was her meeting with Donald Trump when she was 27 and he was 60, and what happened since that has brought her to worldwide attention.
The former US President is facing criminal charges over allegations that he paid her $130,000 (£105,000) not to talk about her claim that the pair slept together and declared it as a business expense. The payment was legal but falsifying business records is illegal in New York state. The decision by New York prosecutors makes him the first serving or former US president to face a criminal charge. He denies any wrongdoing.
Ms Daniels alleges that the payment was made in 2016 just before Trump became president. She alleges that their encounter had been ten years earlier after she had appeared in a Judd Apatow film called the 40-year-old virgin and was invited to a charity golf tournament in Lake Tahoe, on the border between California and Nevada, where she met Mr Trump.
