US President Joe Biden's administration has moved to defend his predecessor Donald Trump in a defamation case put by a woman who accuses him of rape.
It is filing an appeal - the Department of Justice (DoJ) lost a bid to defend Mr. Trump while he was still president.
The new administration argued that it should represent Mr. Trump as nearly everything he said and did as president was a matter of government action.
Columnist E Jean Carroll accuses Mr. Trump of assaulting her in the 1990s.
In the lawsuit filed in 2019, she argues the now ex-president defamed her when he denied her claim and said she was "totally lying".
In October 2020, a federal judge dismissed an effort by the DoJ to put itself in the dock as a defendant instead of Mr. Trump.
Then on Monday the DoJ filed documents with a federal appeals court in New York City to overturn that decision.
Reacting to the latest development, Ms. Carroll said: "As women across the country are standing up and holding men accountable for assault the DOJ is trying to stop me from having that same right. I am angry! I am offended!"
- The sexual allegations against Donald Trump
Mr. Trump has so far made no public comments on the issue.
What arguments has the DoJ used?
"Speaking to the public and the press on matters of public concern is undoubtedly part of an elected official's job," the DoJ brief argued.
"Courts have thus consistently and repeatedly held that allegedly defamatory statements made in that context are within the scope of elected officials' employment - including when the statements were prompted by press inquiries about the official's private life."
DoJ lawyers are quoted by NBC News as stating that Mr. Trump was "crude and disrespectful" in questioning Ms. Carroll's credibility and that comments attacking her appearance, impugning her motives, and implying that she had made false accusations "were without question unnecessary and inappropriate".
But, they said, they "all pertained to the denial of wrongdoing".
What does E Jean Carroll allege?
She says the attack happened at a Bergdorf Goodman store in Midtown Manhattan in late 1995 or early 1996 when the pair bumped into each other while shopping.
The former Apprentice star and real estate magnate allegedly asked her for advice when buying lingerie for another woman and jokingly asked her to model it for him.
In the changing rooms, she said Mr. Trump lunged at her, pinned her against a wall, and forced himself on her.

Ms. Carroll claims she managed to push him off after a "colossal struggle".
Both Mr. Trump and Ms. Carroll were aged around 50 at the time, and he was married to Marla Maples.
Mr. Trump has publicly denied the allegation several times, including saying that Ms. Carroll was "totally lying" and "not my type".
