In what was supposed to be an event focusing on manufacturing jobs, Trump spent a significant amount of time slamming Harris for her border visit as "ridiculous."

Directly blaming Harris for a number of border issues, Trump vowed to hold Harris "accountable for these crimes" and she "will be sent back to California" after the election.

He also further discussed his meeting earlier Friday with Zelenskyy, again suggesting he'll quickly end the war despite him not providing specifics on how he'd do so.

"I will settle the war in Ukraine. I met with President Zelensky today, a good meeting ... We're going to make a settlement, believe me, and I will end the chaos in the Middle East," Trump claimed.

Unlike the Biden-Trump and Harris-Trump debates, the microphones will not be muted.

Harris is out with a new ad blasting Trump over his "broken promises" to autoworkers ahead of his town hall in Warren, Michigan, as she hints she would look to scrap one of his signature trade deals.

The digital ad juxtaposes a clip of Trump promising at a 2016 rally that if elected, "You won't lose one plant, you'll have plants coming into this country, you'll have jobs again," to the closure of a Stellantis plant in that town two years later. (Stellantis owns the Chrysler, Jeep and Dodge brands.)

In a statement overnight, Harris lambasted the United States-Mexico-Canada Agreement, the trade deal Trump renegotiated to replace the Clinton-era North American Free Trade Agreement.

"Once again, he is repeating the same playbook and telling the same old lies about how he'll fight for working people, including those in Michigan," Harris said of the former president. "Yet it was Trump's trade deal that made it far too easy for a major auto company like Stellantis to break their word to workers by outsourcing American jobs. As one of only 10 senators to vote against USMCA, I knew it was not sufficient to protect our country and its workers."

"Many who voted for this deal conditioned their support on a review process, which as president I will use," Harris said. The agreement is up for review in 2026, when parties can choose whether or not to extend it.

United Auto Workers President Shawn Fain, who endorsed Harris, told reporters Friday that her statement was "spot on."

"It's criminal that Donald Trump shows up in places like Flint, Michigan, and Warren, Michigan, or anywhere else in this country, Pennsylvania, Ohio, Wisconsin, and wants to tell workers how much he cares about them, that he's got their back," Fain said. "He doesn't give a damn about working class people, especially auto workers."

Trump and Zelenskyy are now meeting at Trump Tower.

"We're going to have a discussion and see what we can come up with, but a great honor to have you," Trump told reporters.

Trump and Zelenskyy then shook hands, with Zelenskyy thanking Trump for the meeting.

"The war in Ukraine has to be stopped and Putin can't win and Ukraine has to prevail. And I want to discuss with you in detail about our plan," Zelenskyy said.
