Adult-film star Stormy Daniels has filed a court motion for US President Donald Trump to testify about her claim that they had a relationship.
Her lawyer wants sworn testimony from Mr Trump about a “hush” agreement the actress says she signed.
The attorney, Michael Avenatti, is also seeking a legal interview with the president’s lawyer.
Ms Daniels alleges she had unprotected sex with Mr Trump in 2006 a year after he married Melania Trump. He denies it.
Mr Avenatti’s motion, filed in a court in the Central District of California early on Wednesday, ramps up the legal duel between the porn star and the president.
