President Donald Trump's lawyers will argue that he has presidential immunity from a defamation case brought by a former contestant on his reality TV show The Apprentice who accused him of unwanted sexual contact.
His lawyers said in a state Supreme Court filing on Monday that they will formally ask for a dismissal or a suspension of the claims made in January by Summer Zervos until he leaves office.
They said the constitution provides immunity for Mr Trump from being sued in state court while he is president.
The lawyers said their position is supported by a long line of US Supreme Court cases requiring courts to show deference to the president and his schedule.
Ms Zervos was a contestant on Mr Trump's reality show in 2006.
She sued after Mr Trump dismissed her claims as "fabricated and made up". Ms Zervos claimed at a news conference in October that Mr Trump had made unwanted sexual contact with her at a hotel in Beverly Hills in 2007.
The lawsuit sought an apology and damages of $2,914.
Mr Trump's lawyers said he denied "these unfounded accusations" and was prepared to show that they were "false, legally insufficient and made in a transparent politically-motivated attack."
They said the allegations were even disputed by a member of Ms Zervos's family.
Ms Zervos is one of several women who made sexual allegations against Mr Trump when he was running for president last year. He has denied their allegations.
After appearing on Mr Trump's show, Ms Zervos said she later asked him for a job. She said they met and he kissed her on the lips and asked for her phone number. She said that during a later meeting at a hotel in California he became sexually aggressive, kissing her and touching her breasts.
During the presidential campaign, a tape emerged of Mr Trump talking about how fame enabled him to grope and try to have sex with women.
On the tape, from the set of the Access Hollywood show and filmed in 2005, Mr Trump says that, when he's attracted to beautiful women, "I just start kissing them. It's like a magnet."
He said that "when you're a star", women allowed this behaviour. "Grab them by the p--," Mr Trump adds. "You can do anything."
During a later presidential debate, Mr Trump denied carrying out any of the actions he was heard talking about on the tape, which he described as locker room talk.
Mr Trump's wife, Melania, blamed Access Hollywood host Billy Bush for what Mr Trump said. She said they were involved in "boy talk, and he was led on, like egged on, from the host to say dirty and bad stuff."
Gloria Allred, the lawyer acting for Ms Zervos, said she did not believe that the president had legal immunity from a defamation lawsuit.
She said that the Supreme Court had addressed the legal immunity issue in a case involving Bill Clinton and "determined unanimously that no man is above the law, and that includes the president of the United States."
"We look forward to arguing this issue in court," she said.
