2024 election live updates: Crowd gathers for Trump's Madison Square Garden rally

The Harris campaign seized on former White House chief of staff and ex-Marine general John Kelly's remarks panning Trump as a "fascist," among other things, convening a press call of former GOP military leaders to sound a similar alarm.

"This is a difficult conversation for me as a lifelong Republican who always, you know, supported the Republican Party until Donald Trump came along," Brig. Gen. Steve Anderson said.

Anderson mocked the fact that Trump "couldn't qualify to be in the military -- he has 34 felony convictions -- so, how can we have the commander-in-chief be in charge of a military that he couldn't possibly join?"

Kevin Carroll, who served as senior counsel to Kelly when he was Homeland Security secretary under Trump, also underscored the seriousness of Kelly's surprisingly public rebuke of his old boss.

"I had the honor of working aside him, and I know him speaking out this way was no small step for him," Carroll said.

"I'm excited about it," Walz told reporters Wednesday on his way in to the Ramsey County Elections office.

Minnesota started early in-person voting Sept. 20 but the governor has been on the campaign trail most of the time since Vice President Kamala Harris picked him as her running mate.

Tim and Gwen Walz also voted early at the same office in 2022.

John Kelly, who served as chief of staff in Trump's administration, described the former president as a "fascist" during an interview with the New York Times.

"Well, looking at the definition of fascism, it's a far right, authoritarian, ultra nationalist political ideology and movement characterized by a dictatorial leader, centralized hypocrisy, militarism, forcible suppression of opposition, belief, natural, social hierarchy," Kelly told the newspaper. "So certainly, in my experience, those are the kinds of things that he thinks will prove work better in terms of running America."

Kelly also said he believed Trump would "love" to be a dictator, and that he was comfortable saying Adolf Hitler "did some good things, too." Kelly also claimed Trump referred to veterans who lost limbs as "losers and suckers."

The Trump campaign pushed back in a statement.

"John Kelly has totally beclowned himself with these debunked stories he has fabricated because he failed to serve his President well while working as Chief of Staff and currently suffers from a debilitating case of Trump Derangement Syndrome. President Trump has always honored the service and sacrifice of all of our military men and women, whereas Kamala Harris has completely disrespected the families of those who gave the ultimate sacrifice, including the Abbey Gate 13," said campaign spokesperson Steven Cheung.

Billionaire businessman Mark Cuban, who has thrown his weight behind Vice President Kamala Harris, told ABC News on Tuesday that he tried to set up a private meeting between Elon Musk and Harris, but her team declined.

Cuban said the campaign passed because "they didn't think Elon Musk could keep the conversation private."

"The things he says about Kamala are so far off I thought it would be beneficial for them to talk," Cuban said of Musk.

If Harris wins the race, Cuban said he'd still try to set up a conversation between Harris and Musk, given that he's one of the "best entrepreneurs." The move is "not political -- it's common sense," Cuban added.
