Obama calls Trump 'wannabe king' at Harris event

Minnesota Gov. Tim Walz, Harris' running mate, is casting his ballot Wednesday in the 2024 election.

Walz is voting with his wife Gwen and their son Gus, who is a first-time voter, according to the campaign.

They will vote early for Harris at the top of the ticket, the campaign said. They will also vote for Sen. Amy Klobuchar, who is seeking a fourth term, and Rep. Betty McCollum as well as other Democratic candidates further down the ballot.

Hope, the governor's daughter, has already cast her ballot in Montana, Walz has said. On Sunday during a stop in Saginaw, Michigan, the governor said that Hope, who lives in Bozeman most of the time but is often out campaigning with him, had recently returned to the state to cast a vote for Democratic incumbent Jon Tester in that critical Senate race.

Harris will continue a media blitz with a 7 p.m. interview airing on Telemundo. In excerpts of the taped interview released on Tuesday, Harris outlined how her economic plans would benefit Latino me and discussed the recent election in Venezuela.

At 9 p.m., Harris will do a live CNN town hall in battleground Pennsylvania.

Trump will be in Georgia, another key swing state, where he'll participate in a 3 p.m. “Believers and Ballots Faith Town Hall." Later, he'll be at a Turning Point Action rally in Duluth at 7 p.m.

At his rally in North Carolina on Tuesday night, Trump praised Chinese President Xi Jinping and remarked on his relationship with Russian President Vladimir Putin.

Trump repeatedly called Xi “a brilliant man" who "runs 1.4 billion people with an iron fist."

"He's a fierce man. I got along with him very well," Trump said. "Putin -- these are people that are tough people. Kim Jong Un, North Korea, nuclear weapons all over the place."

The comments came after Trump's former chief of staff John Kelly warned he believed Trump would rule as a dictator if elected to a second term in an interview with The New York Times.

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.
