As two more women came forward Friday with allegations of sexual assault by Donald Trump, the Republican presidential nominee used a campaign appearance in North Carolina to discredit his growing list of accusers as part of a vast media conspiracy against him, and insulted two of them as too unattractive for him to have groped.

“Believe me, she would not be my first choice,” Trump said of Jessica Leeds, 74, who alleged in a bombshell New York Times story Wednesday that the real-estate billionaire had grabbed her breasts and stuck his hand up her skirt while seated next to her on a flight in the 1980s.

He also mocked Natasha Stoynoff, a writer for People who alleged in a first-person account, also published Wednesday night, that Trump had forced himself on her during an interview in 2005. “Check out her Facebook page, you’ll understand,” he jeered, standing before a crowd of thousands of supporters at the White Oak Amphitheater in Greensboro. Trump also appeared to insult the appearance of his Democratic rival, Hillary Clinton, telling the audience that when she walked in front of him during the last presidential debate, “believe me, I wasn’t impressed.”

Continuing to rant, Trump claimed that journalists at The New York Times, which published allegations made by Leeds and another woman, Rachel Crooks, were “corporate lobbyists for Carlos Slim and Hillary Clinton,” referring to the paper’s largest individual share holder and Trump’s Democratic rival for the presidency. In recent days, Trump has targeted Slim, a Mexican billionaire, as part of a shadowy alliance of global elites trying to sabotage his candidacy. “We’ve seen this firsthand in the WikiLeaks documents in which Hillary Clinton meets in secret with international banks to plot the destruction of U.S. sovereignty in order to enrich these global financial powers, her special-interest friends, and her donors,” Trump said at a rally Thursday.

While Trump has sought to portray his accusers as liars seeking fame, the list of his accusers continues to grow. Even as Trump was campaigning in North Carolina, two more women came forward with allegations of sexual assault at the hands of the G.O.P. nominee: one a former model who claims that the billionaire unexpectedly reached up her skirt while she was at a nightclub, and the other a former Apprentice candidate who said she had been assaulted while seeking a job with the Trump Organization.
