LOS ANGELES - Adult-film actress Stormy Daniels sued President Donald Trump on Wednesday, alleging he never signed a nondisclosure agreement to keep her quiet about an "intimate" relationship between them.

Trump has denied having an affair with Daniels.

Daniels, whose real name is Stephanie Clifford, filed the lawsuit in Los Angeles claiming the agreement is invalid and she is free to publicly discuss her relationship with Trump.

The lawsuit, which Clifford's attorney Michael Avenatti published in a tweet, says that she signed both the agreement and a side letter using her stage name on Oct. 28, 2016, days before the 2016 US presidential election.

Trump's attorney Michael Cohen signed the document the same day, but Trump never signed the document, the lawsuit claims.

The "hush agreement" as it is called in the lawsuit refers to Trump as David Dennison and Clifford as Peggy Peterson. The side letter agreement reveals the true identities of the parties as Clifford and Trump, according to the lawsuit.

Clifford asks in the lawsuit for the Los Angeles County Superior Court to declare the agreement and side agreement invalid and unenforceable. - AP
