Obama calls Trump 'wannabe king' at Harris event

In a town hall hosted by NewsNation outside of Detroit, Michigan, vice presidential nominee Sen. JD Vance took questions from undecided voters in the crowd about what a second Trump administration would tackle and like to accomplish.

In an unexpected moment, former President Donald Trump called into the town hall and asked Vance, "How brilliant is Donald J. Trump?"

"This is supposed to be undecided voters," Vance joked. I would hope that I have your vote of all people."

"Sir, of course, you're very brilliant and we both agree that it's important to have very smart people running our government," Vance said.

Trump also asked Vance how brilliant Vice President Kamala Harris was, leading Vance to say that's "a tough one."

"Don't say it," Trump said. "We don't need anymore. We're doing just fine."

Trump praised Vance, saying he's doing a "fantastic job" and couldn't be happier with him.

Vance was asked three different times throughout the evening what he would do if he were to become president over the next four years if something happened to Trump.

Vance quickly pivoted back to Trump, saying he is "as healthy as an ox" and will be able to
complete a full term if elected back to the White House.

"There's no chance that he's not going to be able to complete a full four-year term. I think he's going to do it. He's going to do it with a ton of energy," Vance said.

"Just look at the campaign schedule that Donald Trump has kept compared to his Democratic opponents. He's doing like three public events for every event Kamala Harris has done," Vance added.

Vice President Kamala Harris and former President Barack Obama teamed up for their first joint rally in Clarkston, Georgia, Thursday, to take swings at former President Donald Trump and implore Georgians to vote early.

"So much is on the line in this election, and this is not 2016 or 2020. The stakes are even higher, because over the last years, and in particular the last eight years, Donald Trump has become more confused, more unstable and more angry," Harris said.

“You see it every day. He has become increasingly unhinged. But last time at least, there were people around him who could control him. But do notice in this election they’re not with him this time," the vice president added.

Obama also hit Trump over his former White House Chief of Staff John Kelly and Joint Chiefs of Staff chairman Gen. Mark A. Milley's recent comments about him.

"They are people who have never in the past even talked about politics because they believe that the military should be above politics. But the reason they’re speaking up is because they have seen that in Donald Trump's mind, the military does not exist to serve the Constitution or the American people," Obama said.

"He doesn't see being commander-in-chief as a solemn, sacred responsibility," Obama continued. "Just like everything else, he thinks the military exists to do his bidding, to serve his interests."

In a message to the audience of the star-studded rally Thursday, Harris said, "Georgia, we need you to vote early, please vote early."

Gov. Tim Walz delivered remarks at a rally in Wilmington, North Carolina, on Thursday centered around an assertion that former President Donald Trump is dangerous and unfit for the Oval Office on the heels of Trump White House Chief of Staff John Kelly's recent remarks about his former boss.

"The people who know Trump best, who sat beside him in the Oval Office, who were in the Situation Room, are now finding the courage to come out of the woodwork and sound the alarm. As I said, Vice President Harris called it a '911 to the American people,' because these insiders know that Donald Trump of 2016 is not the Donald Trump of 2024," Walz warned.

Walz reiterated that there will be no guardrails in a second Trump term and that he’d be given virtually unchecked power by the Supreme Court, which could even become more conservative.

“When he says he wants to be a dictator on day one of his presidency, he's not just saying it, he's promising it. I've been saying it, and I think you feel it. You've seen it over the last few weeks. Hell, we've seen it over the last nine years, but certainly the last few weeks. This is a straight-up descent into madness in front of us, and he's repeatedly talking about it," Walz said.

Former President Barack Obama took the stage in Atlanta following a performance from Bruce Springsteen and speeches from Tyler Perry and Sen. Raphael Warnock repeating his message to get Georgians to vote.

Obama wasted no time bashing former President Donald Trump over his policies and rhetoric.

"We know this election is going to be tight because a lot of Americans are still struggling," he said. "What I cannot understand ... why anybody would think that Donald Trump would be able to shake things up for you."

Obama ripped into Trump for his rambling speeches, peddling of products such as shoes and bibles, stating "All he cares about is his ego."

"Just because he acts goofy doesn't mean his presidency wouldn't be dangerous," he warned.

Obama brought up the recent comments by Trump's former Chief of Staff John Kelly and Trump's claims to go after the "enemy within."

"Unlike the first time, he won't have people like John Kelly around to stop him. He'll have people who are just as looney as he is, and let him do what he wants" he said.

Obama touted Vice President Kamala Harris as the candidate who listens to the people and "is ready for the job."

"If you elect Kamala Harris, she will not be focused on her problems, her ego, her money. She's going to be focused on you," he said.
