Election 2024 updates: Trump campaign claims it was hacked by 'foreign sources'

Vice President Kamala Harris has addressed criticism from Sen. JD Vance on her running mate, Gov. Tim Walz, and his military record.

Speaking with reporters in Detroit, Michigan, Harris said, "Listen, I praise anyone who has presented themselves to serve our country. And I think that we all should."

Harris’ comments come after Vance, the running mate of former President Donald Trump, accused Walz of "stolen valor," saying he lied about his military service when he never saw active combat.

The Harris-Walz campaign issued a statement Wednesday saying that "in his 24 years of service, the Governor carried, fired and trained others to use weapons of war innumerable times. Governor Walz would never insult or undermine any American's service to this country -- in fact, he thanks Senator Vance for putting his life on the line for our country. It's the American way."

The major party vice presidential nominees -- Democrat Gov. Tim Walz and Republican Sen JD Vance -- sharply disagree on a range of issues, but the differences in their personal finances are just as stark.

Walz, a former teacher and member of the U.S. House of Representatives, earns about $127,000 in salary per year, retains no stock holdings and relies on a pension account as his primary asset, financial disclosures show.

Vance, a former venture capitalist, brought in roughly $221,000 in 2022 from salary and book royalties, as well as hundreds of thousands in investment income, a U.S. Senate financial disclosure showed. He also held significant wealth in brokerage accounts and dozens of business investments, according to the financial disclosure.

Former President Donald Trump said he has agreed to an offer from ABC News to debate Vice President Kamala Harris on Sept. 10.

He said so during a news conference at his Mar-a-Lago Club on Thursday.

Trump previously said he had been willing to go toe-to-toe with President Joe Biden and agreed to ABC News' first invitation issued in May.

However, after Biden dropped out of the race last month and Harris became the presumptive Democratic nominee, Trump had implied he would not debate Harris on ABC.

Harris has accused Trump of "running scared" and trying to back out of the debate.

Harris and Walz will attend a campaign event with United Auto Workers members in Wayne, Michigan, which represents Ford’s Michigan Assembly Plant Thursday afternoon, the campaign said.

Upon arrival, they will be greeted by President Shawn Fain and UAW board members, according to the campaign, before they deliver brief remarks.

The union endorsed Harris for president on July 31 after it had previously endorsed Biden.

This stop is their only campaign stop before heading to Phoenix, Arizona, for a rally on Friday.
