Trump says he 'shouldn't have left' the White House

Vice President Kamala Harris opened her remarks in Michigan by acknowledging the ongoing war in the Middle East, saying, "It is devastating."

Harris held a rally at Michigan State University on Sunday with just two days left in the 2024 presidential race.

"This year has been difficult, given the scale of death and destruction in Gaza and given the civilian casualties and displacement in Lebanon," Harris said.

The vice president said that if elected, she "will do everything" in her power to bring the conflict to an end.

"It is devastating, and as president, I will do everything in my power to end the war in Gaza, to bring home the hostages, end the suffering in Gaza, ensure Israel is secure and ensure the Palestinian people can realize their right to dignity, freedom, security and self-determination," Harris said.

At his second campaign stop of the day, former President Donald Trump lost the crowd after arriving two hours late to his rally -- with a massive number of people leaving just minutes into his speech.

It’s common to see supporters trickling out toward the end of his speeches, but the surge of supporters that headed for the exit at this rally, especially so early on, was unprecedented.

Hundreds of people continued to leave the rally throughout his speech, even those seated in the prime bleacher spots right behind Trump. Seated sections noticeably thinned out, and the standing section only had a few rows of people.

Many people exiting said they were leaving early because they had other commitments to get to or had just been standing outside in the sun for too long.

During a campaign rally in Pennsylvania on Sunday, former President Donald Trump said that he "shouldn't have left" the White House after losing the 2020 election to President Joe Biden.

“I shouldn’t have left. I mean, honestly, because we did so, we did so well,” Trump said while discussing U.S.-Mexico border security.

Second gentleman Doug Emhoff, while stumping ahead of Gov. Tim Walz at a rally in metro Atlanta on Sunday, reacted to Trump's comments, saying "I couldn't believe it."

"Trump said he shouldn't have left the White House at the end of his term. He said that. He just said it an hour or so ago -- imagine that," Emhoff said.

"We need to take this very seriously right now. I mean, we're right at the end, and I know you all see that, and what we need to talk to some of these folks that just don't quite get it yet... what an actual threat this guy is, because you gotta listen to what he's saying," Emhoff added.

Minnesota Gov. Tim Walz and second gentleman Doug Emhoff held their first joint event of the campaign cycle on Sunday, just two days out from Election Day in Gwinnett County, Georgia -- critical ground for Vice President Kamala Harris as she attempts to win the presidency on Tuesday.

The event also featured Harris' sister, Maya, and musical performances by Jon Bon Jovi, The War and Treaty and Michael Stipe. It was a high-energy affair, and when Walz asked who had already voted in the room of about 1,400 people, nearly every hand went up -- an anecdote consistent with the record early voting numbers Georgia has been reporting.

"Here's the deal, Georgia, you have the potential to win this whole damn thing," Walz said.

Walz also warned the crowd that GOP House Speaker Mike Johnson had said Republicans might seek to repeal the CHIPS and Science Act if they take control of Congress this cycle.

"Listen to this -- defunding 115,000 jobs that are already working in manufacturing and construction, including 1,200 good paying jobs right here in Georgia," Walz said. "This thing is not only important for jobs, it is critical that we win the competition of the 21st century from countries like China."
