In the video, Mr Trump was shown a photo of himself speaking to other people at an event. "It's Marla," he says, before his lawyer corrects him.
"No, that's Carroll," the lawyer says.
Ms Carroll, 79, has accused Mr Trump, 76, of attacking her in a New York City department store in the mid-1990s, an allegation Mr Trump has denied.
Lawyers for Ms Carroll have argued that Mr Trump's confusion over the photo undermines his claim that Ms Carroll is "not my type", a comment he has repeated since she first came forward with the allegation in 2019.
