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

President Joe Biden rallied union voters and skewered Vice President Kamala Harris's Republican opponents in a trip to his hometown of Scranton, Pennsylvania, Saturday, delivering remarks at a Carpenters Local 445 GOTV event.

Biden told supporters that Trump and his allies wanted to repeal the Affordable Care Act and CHIPS And Science Act, slash taxes for the wealthy and cut Social Security benefits if they secured power in this election.

"We've been through a lot together. Not only have you been my allies in labor, you've been my friends," Biden said, beginning his pitch for Harris.

"Three days to election day, the stakes couldn't be higher. The choice couldn't be clearer. A lot of politicians have trouble saying the word, 'union.' But I'm not one of them. By the way, neither is Kamala," he said.

Biden segued into tax policy, accusing Republicans of trying to cut taxes for wealthier earners.

"There's one more thing Trump and his Republican friends want to do they want another giant tax cut for the wealthy," Biden said.

“Now, I know some of you guys are tempted to think it's macho guy. I'll tell you what, man, when I was in Scranton, we used to have a little trouble going down The Plot once in a while,” Biden said, referring to a neighborhood in Scranton.

"These are the kind of guys you'd like to smack in the a**,” he added, grimacing as the crowd cheered.

Vice President Kamala Harris tore into former President Donald Trump almost immediately upon taking the stage at her Atlanta rally Saturday afternoon.

"Look, we know who Donald Trump is," she said. "Because we know this is not someone who is thinking about how to make your life better. This is someone who is increasingly unstable, obsessed with revenge, consumed with grievance."

Harris touted her commitment to "listen to experts and to listen to people who disagree with” her, contrasting herself with Trump.

"I will give them a seat at the table," she said.

The North Carolina State Board of Elections put out a statement earlier Saturday "in response to reported confusion among some naturalized citizens about their eligibility to vote."

"It does not matter if you were born a U.S. citizen or were naturalized or acquired citizenship. And it does not matter if you are a citizen, but your family members are not. Citizenship is citizenship, and it pertains to you," the statement, which was posted in English and Spanish, said.

The Georgia Secretary of State announced Saturday that over 4 million people voted early in the key battleground state, calling it "the most successful Early Voting period in Georgia history."

"As of Saturday morning, 92 Georgia counties have exceeded 50% turnout. This is unprecedented in Georgia history," the office said in a statement.

Meanwhile, the office said it had identified four people who may have attempted to vote multiple times during that period-- an incident they say is now under investigation and shows that "safeguards" in the state work.

"If the investigation shows violations of the law, the office will refer the individuals to local District Attorneys," the office said.
