Donald Trump unleashed a deeply personal string of attacks Thursday against the women who have accused him of groping or kissing them without their consent, labeling them “horrible, horrible liars” and telling his supporters to “look” at one of his accusers and decide if she is telling the truth.

“You take a look. Look at her. Look at her words. You tell me what you think. I don’t think so,” the Republican presidential nominee said, singling out former People magazine reporter Natasha Stoynoff, who wrote Wednesday that Trump kissed her without her consent at his Mar-a-Lago resort when they were alone before an interview with him and his wife, Melania, in 2005.

The rhetorical salvo came as Trump faced allegations from Stoynoff and three other women in Wednesday news reports, all of which he denies.

“These people are horrible people. They’re horrible, horrible liars. And interestingly, it happens to appear 26 days before our very important election,” Trump said.

Trump’s treatment of women is under intense scrutiny. The Washington Post reported a 2005 video on which he can be heard making vulgar comments about forcing himself physically on women.

He said at Sunday’s presidential debate that he never engaged in the behavior he was talking about on the tape. The women who came forward with their allegations this week in news reports said that comment bothered them.
