Harris campaign hits Trump on age in ad labeling JD Vance an "extremist"

• Previously, Democrats had only hinted at this and the most notable attacks had come from former GOP presidential candidate Nikki Haley, who targeted both 78-year-old Trump and 81-year-old President Biden.

Driving the news: The 50-second ad that targets voters in battleground states features clips of Vance's previous comments, including when he said in 2022 that he "certainly would like abortion to be illegal nationally." He has since publicly concurred with Trump's latest stance on leaving abortion policy to states.

• "He's not just weird or dangerous, he could be a heartbeat away from the Oval Office," says the narrator in the ad, who calls Vance "a danger to our democracy."
• It features a Fox News journalist saying Trump has "been off his game" as it shows the former president tripping over his words.

• The Trump campaign did not immediately respond to Axios' request for comment.

Between the lines: The ad also seeks to link Vance to the Heritage Foundation-backed "Project 2025."

• Harris' running mate Minnesota Gov. Tim Walz is expected to try to tie the Republican ticket to the project during the debate Tuesday.
• Trump has been distancing himself from the project that some of his allies have contributed to.
