Trump is challenging a March 20 ruling by Justice Jennifer Schecter of State Supreme Court in Manhattan allowing the case to proceed. A preliminary conference before Schecter is scheduled for June 5, court records show.
In a filing on Monday, Trump told the state's Court of Appeals that the lawsuit by Summer Zervos should be put on hold because a sitting U.S. president is immune from being sued in a state court during his term in the White House.
In another filing late Tuesday night, Trump formally answered the complaint, and again denied the allegations or said he did not have enough information to form a belief.
Saying "no one is above the law," Schecter rejected Trump's claim of immunity over private conduct predating his becoming president.
An intermediate state appeals court on May 17 refused to halt Zervos' lawsuit, without ruling on its merits.
Trump said that refusal qualified as a "final appealable order" justifying intervention by the Court of Appeals.
"We look forward to proving (the) defendant lied when he attacked Ms. Zervos for telling the truth about his unwanted sexual groping," Wang added.
Zervos accused Trump of subjecting her to unwanted kissing and groping after she sought career advice in 2007.
She came forward during the 2016 presidential campaign, and Trump called such allegations by women "lies." He also retweeted a post calling Zervos' claims a "hoax."
Zervos said Trump defamed her by branding her a liar. She is seeking a retraction or an apology, compensatory damages and punitive damages in her lawsuit.
In addition to presidential immunity, Trump's lawyer Marc Kasowitz argued that the alleged defamatory statements were also "privileged or protected by one or more immunities, including, but not limited to, under the Constitution of the United States," among other defenses.
