Former California Gov. Arnold Schwarzenegger announced Wednesday that he was going to vote for Vice President Kamala Harris.

"The Terminator" actor and longtime Republican said in lengthy X post that he didn't like either party now given the divisions and lack of progress from leaders in Washington, D.C.

However, Schwarzenegger said he was "furious" over Trump's refusal to accept the 2020 election, anti-immigrant rhetoric, economic policies and actions on Jan. 6.

"We need to close the door on this chapter of American history, and I know that former President Trump won't do that. He will divide, he will insult, he will find new ways to be more un-American than he already has been, and we, the people, will get nothing but more anger," he said.

"That's enough reason for me to share my vote with all of you. I want to move forward as a country, and even though I have plenty of disagreements with their platform, I think the only way to do that is with Harris and Walz," he said.

Nikki Haley recently said she is ready to campaign for Trump, despite not talking to him since June.

Trump's running mate, Sen. JD Vance, when asked about whether Haley will make an appearance, said Tuesday he would "love" to see her on the trail, but said it was up to her schedule.

Haley was Trump's last major challenger in the Republican primary. Despite hitting him hard in the final weeks of her campaign, she later endorsed him at the Republican National Convention.

And she's continued some criticism of his campaign strategy. During an appearance on Fox News, she said the racist remark about Puerto Rico by a comedian at Trump's Madison Square Garden rally was "harmful" and that the campaign "need[s] to go and tell Puerto Ricans how much, you know, they do value them."

She also said the Trump team had to improve its messaging to women.

"I mean, that this bromance and this masculinity stuff," she said. "I mean, it borders on edgy to the point that it's going to make women uncomfortable. You know, you've got affiliated PACs that are doing commercials about calling Kamala the 'C-word,' or you had speakers at Madison Square Garden, you know, referring to her and her pimps."

"That is not the way to win women. That is not the way to win people who are concerned about Trump style," Haley added.

On the tarmac at Joint Base Andrews about to depart for a day of campaigning, Harris was asked about President Joe Biden's "garbage" comment seeming to refer to Trump supporters. The White House and Biden have said he was specifically referring to the racist remarks made by some speakers at Trump's Madison Square Garden rally.

"Listen I think that first of all, he clarified his comments," Harris said. "But let me be clear, I strongly disagree with any criticism of people based on who they vote for."

"You heard my speech last night and continuously throughout my career, I believe that the work that I do is about representing all the people, whether they support me or not," she said. "And as president of the United States, I will be a president for all Americans, whether you vote for me or not."

It's a state that could tip the result of the 2024 election.

And Trump is ramping up rhetoric sowing doubt on the state's voting process.

In a post on his social media site on Wednesday morning, Trump claimed there's "cheating" happening at "large scale levels." He did not elaborate or provide evidence for his claims.

Some isolated incidents have emerged, including approximately 2,500 potentially fraudulent voter registration applications being investigated in Lancaster County, though officials stressed the system worked and that voters can be confident in the election.
