Obama calls Trump 'wannabe king' at Harris event

As Republicans attempt to encourage early voting, Trump called into Fox News host Brian Kilmeade's radio show to say he'll vote early, but he continued to show reluctancy about the practice.

"I'm very mixed on it. I mean, I'm OK with the Tuesday voting, which they like doing, Republicans like, and I'm also, I say, the main thing I say is vote," he said.

Trump also reiterated his baseless claims about cheating in this election cycle, saying it was his biggest concern when he was asked which of the battleground states worried him most.

"All of them. I mean, did they cheat? All of them? I mean, the biggest risk to me," Trump said. "I think we win it easily."

Gov. Tim Walz, his wife Gwen Walz and their son Gus Walz voted early in St. Paul on Wednesday. The precinct cheered for Gus Walz as he voted for the first time.

"Exciting, an opportunity to turn the page on the chaos of Donald Trump and a new way forward,” Tim Walz said in brief remarks following the vote.

The Harris-Walz campaign continues to court young voters, announcing a college campus tour in swing states intended to promote early voting.

“This week, Team Harris-Walz is launching the ‘Vote for Our Future’ early vote college campus tour to mobilize young voters on college campuses across battleground states, encouraging them to make their voices heard, register to vote, and vote early,” the campaign told ABC News.

Officially launched Friday, the early vote campus tour includes a new seven-figure targeted ad buy for battleground college students, as well as concerts, block parties, food and campaign merch.

In addition to second gentleman Doug Emhoff and Maya Harris hosting an early vote mobilization event and concert near the University of North Carolina campus Tuesday evening, Gov. Tim Walz will also visit Duke University in North Carolina on Thursday, the campaign said.

Additional events at Michigan State University, Indiana University of Pennsylvania, and University of Michigan are scheduled for this week.

These efforts are coupled with a seven-figure ad buy that targets students in battleground states through social media ads and out-of-home ads on campuses, the campaign said.

On Wednesday, the DNC also announced an expansive, mid-six-figure ad campaign targeting young voters on college campuses across battleground states and directing them to IWillVote.com, according to a press release.

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.
