Biden talks about passing torch in address

Vice President Kamala Harris thanked President Joe Biden for endorsing her in the 2024 presidential race on Monday.

"It is my great honor to have Joe's endorsement in this race," Harris said while speaking to campaign staff in Delaware.

Echoing Biden's comments on his commitment to the Democratic campaign, Harris said, "Joe is not done, far from it."

"He knows there is still more work to do and our nation will continue to praise his bold and visionary leadership as president," Harris said, adding, "Thank you, Joe."

Harris also went on the attack against Donald Trump at her campaign event in Delaware on Monday.

President Biden called in to speak with Kamala Harris' campaign HQ on Monday, saying he "isn't going anywhere" after announcing Sunday that he's stepping aside from his reelection bid.

"The name has changed at the top of the ticket, but the mission hasn't changed at all," Biden said over the phone. "And by the way, I'm not going anywhere. I'm going to be out there on the campaign with her," he added.

"I'm going to be working like hell, both as a sitting president, getting legislation passed, as well as in campaigning," Biden said.

While Republicans promoted a unifying message last week and decried inflammatory language in the wake of the assassination attempt against former President Donald Trump, one of the first speakers to introduce Republican vice presidential nominee JD Vance at a rally on Monday suggested the country may need to come to civil war if Trump loses in November.

"I believe wholeheartedly, Donald Trump and Butler County's JD Vance are the last chance to save our country," said George Lang, a Republican state senator. "Politically, I'm afraid if we lose this one, it's going to take a civil war to save the country and it will be saved. It's the greatest experiment in the history of mankind."

Lang later apologized after Harris' team highlighted his remarks on a post on X.

"I regret the divisive remarks in the excitement of the moment on stage," he said on the same social network. "Especially in light of the assassination attempt on President Trump last week, we should all be mindful of what is said at political events, myself included."

Kamala Harris' presidential campaign has surged in the 24 hours since announcing her candidacy, with 28,000 volunteers signing up to help organize, according to her campaign.

The boost in efforts is more than 100 times than on an average day, according to campaign officials.
