Obama calls Trump 'wannabe king' at Harris event

Vice President Kamala Harris participated in a series of moderated conversations with former Rep. Liz Cheney in Pennsylvania, Michigan and Wisconsin on Monday.

In those appearances, Cheney made a case for conservatives to vote Democrat in the upcoming election and support Harris' bid for the White House.

"What I would say is that if people are uncertain, if people are thinking, 'Well, you know, I'm a conservative, I don't know that I can support Vice President Harris,' I would say, I don't know if anybody is more conservative than I am," said Cheney, who was the third-ranking member of the House Republican Conference from 2019 to 2021.

Cheney also warned Republicans considering voting for Trump that Congress would not be a check on him.

"For anybody who is a Republican who is thinking that, you know, they might vote for Donald Trump because of national security policy, I ask you, please, please study his national security policy," Cheney said. "Not only is it not Republican — it's dangerous. And without allies, America will find our very freedom and security challenged and threatened."

"And one final point on this: Don't think that Congress can stop him," Cheney added.

In Malvern, Pennsylvania, Cheney said she thought there would be Republican voters who would cast their ballots for Harris — even if they did not reveal it publicly.

In Michigan, she went further, encouraging voters to do just that, saying, "If you're at all concerned, you can vote your conscience and not ever have to say a word to anybody, and there will be millions of Republicans who do that on Nov. 5, vote for Vice President Harris."

Rallying in Greenville, North Carolina, on Monday, Trump launched baseless claims about possible fraud in the 2024 election -- despite earlier in the day saying he hadn't seen evidence of it.

At one point during the rally, Trump turned to Republican National Committee Chairman Michael Whatley to ask him about election security.

"He'll stop the cheating. He's going to stop the cheating," Trump said to Whatley. "Are they cheating? Michael, they're trying, but are they? They're not going to get away with it, right? ... They got away with it in plenty of places."

Earlier in Asheville, North Carolina, Trump told his supporters that he hasn't seen any evidence of cheating in the election thus far, but added, "I know the other side and they are not good."

The office of the Georgia Secretary of State announced Monday that more than 1.5 million voters have voted early in person in Georgia as of Monday afternoon.

“Georgia voters know we’ve made it easy to cast a ballot. It’s really that simple,” Georgia Secretary of State Brad Raffensperger said in a statement.

In-person early voting started in the key battleground state on Tuesday, Oct. 15.

As of Monday afternoon, more than 15 million early votes have been cast nationally, including almost 5 million in-person early votes, according to an analysis by the Election Lab at the University of Florida.

On her way to her moderated conversation in Michigan, Harris was asked if she had worked at a McDonald’s while deplaning Air Force 2.

“Did I? I did," she said.

Her past experience at McDonald's has become a fixation of Trump's, who over the weekend worked the fryer at one of the chain's restaurants in the Philadelphia area.

Trump has claimed Harris never worked at the fast food giant. Harris, in introducing herself to voters this campaign, has told the story of working there between her freshman and sophomore years at Howard University in an effort to contrast her working-class roots with Trump's background.
