Trump posts about a new debate plan, and Harris pushes back

Vice President Kamala Harris responded to former President Donald Trump after he posted on social media about switching the date and format of the next televised presidential debate, saying she'd see him at the event "he already agreed to." Then Trump doubled down.

"I’ll see her on September 4th or, I won’t see her at all," he posted on his Truth Social platform, referring to a debate he says he agreed to with Fox News.

Trump, the GOP nominee for president, had originally agreed to debate President Biden on Sept. 10 on ABC News, but late Friday, Trump wrote that he had "agreed with Fox News" to debate Harris on Fox News instead, on Sept. 4.
