Former President Trump announced Monday he will do a “personal play by play” of the vice presidential debate Tuesday evening.

“I will be doing a personal PLAY BY PLAY of the Debate tomorrow between the Brilliant J.D. Vance and the Highly Inarticulate ‘Tampon’ Tim Walz,” Trump posted to his Truth Social site.

Trump’s running mate, Sen. JD Vance (R-Ohio), is set to debate Vice President Harris’s running mate, Minnesota Gov. Tim Walz (D), in the vice presidential debate Tuesday in New York City.

The debate will be hosted by CBS News and will take place at 9 p.m. EDT and run for 90 minutes with two four-minute breaks.

Trump, who posts often on Truth Social, said he will be watching Vance and Walz debate and hopes Harris will be tuning in too.

“I hope that Cognitively Challenged, Lyin’ Kamala Harris, will be listening so that she can again show the World how she will make up false facts and stories in order to change around an administrative FAILURE!” Trump’s post said.

“In any event, I will be commenting on what is going on. Watch TRUTH SOCIAL tomorrow night!” the post concluded.

With fewer than 40 days until the election, the debate between Vance and Walz could prove to be critical. It’s seen as one of the last opportunities for the Harris and Trump campaigns to appeal to voters who may still be on the fence.

After Harris and Trump debated earlier this month, which was widely viewed as a win for the vice president, Trump declined to accept another debate. He declared on Truth Social that there “WILL BE NO THIRD DEBATE,” after he took the stage against both Harris and President Biden before he dropped out.

Harris is holding razor-thin leads in several swing states, but pollsters caution that the race is still a toss-up. According to The Hill/Decision Desk HQ, Harris leads with 50 percent to Trump’s 45.8 percent.

The high-stakes debate Tuesday will mark the biggest political moment of both Vance's and Walz’s careers, as they seek to introduce themselves to voters but also make the case for their campaigns.
