Trump says he 'shouldn't have left' the White House

At an Arab-owned breakfast restaurant in Dearborn, Michigan, former President Donald Trump continued to attack Liz Cheney, claiming she’d “chicken out” if she were to be put into a battle.

"All she wants to do is blow people up. She’s a war hawk and a dumb one at that," he said.

“They don't mind killing people, but if they had to do it themselves – she wouldn't fight, she's a coward,” Trump continued.

Trump dodged several questions about his reaction to Vice President Kamala Harris calling his comment on Cheney "disqualifying."

Trump also repeatedly dodged questions about Robert F. Kennedy Jr.’s views on vaccines, reiterating Kennedy is going to have a “big role” in health care and that he’ll be talking about “a lot of things” with him.

"He knows it better than anybody. He's got some views that I happen to agree with very strongly, and I have for a long time," Trump said while not elaborating.

"All of these things will be talked about," Trump said, again pressed on Kennedy’s vaccine stance.

The former president, who tried to push for a ban on Muslim immigrants in his first term, touted support from Arab Americans, especially Lebanese Americans in Dearborn.

He said he wants "peace" in the world but dodged a question about the Muslim ban from his previous administration.

"We're looking for their votes, and I think we’ll get their votes," Trump said.

Speaking at an electrical workers union in southern Wisconsin Friday, Vice President Harris stressed the importance of the next four days before Election Day.

“Nobody can sit by the sidelines,” she urged.

Harris said her priority is “bringing down your cost of living," reiterating she will "always put the middle class first."

The vice president discussed her intent to “eliminate unnecessary degree requirements for federal jobs.”

“And I will challenge the private sector to do the same,” she said.

Harris cited the Foxconn facility former President Donald Trump had promised to build in Wisconsin, but which never materialized – an example she used to label him, “All talk, no walk.”

"He said Wisconsin would soon be home to a manufacturing plant that he called again, Donald Trump language, 'the eighth wonder of the world,'" she said.

Harris urged the union workers to “pay attention to what [Trump] has actually done.”

"Here's the bottom line, Donald Trump's track record is a disaster for working people, and he is an existential threat to America's labor," she said.

Arizona Attorney General's Kris Mayes is looking into whether former president Donald Trump comments about Rep. Liz Cheney violated state law, her office told ABC News Friday.

Trump called Cheney a "war hawk" and said she should face "nine barrels," appearing to suggest a firing squad.

Mayes' office did not immediately provide further details about their probe.

Trump is offering a similar spin as his campaign on his criticism of Liz Cheney's position on U.S. military entrance into foreign countries.

"All I'm saying about Liz Cheney is that she is a War Hawk, and a dumb one at that, but she wouldn't have 'the guts' to fight herself," Trump wrote on his social media platform.

"It's easy for her to talk, sitting far from where the death scenes take place, but put a gun in her hand, and let her go fight, and she'll say, 'No thanks!'" Trump wrote.
