Mr. Trump has been rattled by the release of the 2005 video recording, according to two people with direct knowledge of his mood who were granted anonymity to candidly describe the situation.

He was urged to be humble, and he felt that he had been, in an apology video that his campaign released early Saturday. But he was criticized for ending his statement with a dig at the Clintons and for not apologizing to his wife, Melania, in his remarks. To him, the criticism was an affirmation that “nothing he can say or do” would reduce the hostility directed his way, according to one of the people with knowledge of how he feels.

Inside the tower on Saturday, different plans of action were discussed. Mr. Trump and his advisers considered a joint television interview that he and Ms. Trump would give to a major network, an echo of the 1992 appearance by the Clintons on “60 Minutes” after Gennifer Flowers claimed that she had had an affair with Mr. Clinton.

The deliberations over a possible interview were moving ahead despite Ms. Trump’s lack of interest in appearing on camera. But then Nancy O’Dell, the former “Access Hollywood” host whom Mr. Trump had lewdly described in the recording, issued a statement denouncing his comments. And then more tapes of Mr. Trump speaking crudely about women, this time on “The Howard Stern Show,” turned up on television.
