Obama calls Trump 'wannabe king' at Harris event

Officials in a Pennsylvania county are warning voters to beware of a fake video circulating on social media purporting to show mail-in-ballots being opened and destroyed ahead of the 2024 election.

"The envelope and materials depicted in this video are clearly not authentic materials belonging to or distributed by the Bucks County Board of Elections," the board said in a bipartisan statement.

The video has been reported to law enforcement agencies, including the FBI and Pennsylvania Department of State.

"This type of behavior is meant to sow division and distrust in our election systems, and makes a mockery of the people working incredibly hard to ensure a free and fair election is carried out. The Board of Elections unequivocally condemns this purposeful spreading of dangerous disinformation. We will not be distracted from the job the voters of Bucks County have entrusted to us," the board said.

At least a dozen voters in Mesa County, Colorado, had their ballots stolen and fraudulently filled out without them knowing, Secretary of State Jena Griswold announced Thursday.

After the stolen mail-in ballots were returned to the clerk’s office via the Postal Service, the state’s voter signature verification system flagged discrepancies with the signatures on some of the ballots, she said. When election officials reached out to the voters to offer them a chance to “cure” the issue, the voters informed the officials that they hadn’t voted, according to Griswold.

Three of the stolen ballots that passed the signature verification process were successfully cast.

"This attempt at fraud was found and investigated quickly because of all the trailblazing processes and tools Colorado has in place like signature verification, ballot tracking, and the curing process," Griswold added. "Every eligible Colorado voter will be able to make their voice heard this election."

The Mesa County District Attorney's Office is investigating the fraud scheme.

Earlier this month, Tina Peters, the former Mesa County Clerk and Recorder, was sentenced to nine years in prison for leading a security breach of the county's election system.

Peters, a Republican, was convicted for giving an individual affiliated with MyPillow CEO Mike Lindell, a Trump ally, access to the election software she used for her county. Screenshots of the software appeared on right-wing websites.

Harris running mate Minnesota Gov. Tim Walz made a quick visit to a canvassing event at the Pitt County Democratic headquarters in Greenville, North Carolina, on Thursday afternoon and delivered a stump speech focused on energizing volunteers.

He also repeated his criticism of Trump wishing he’d had generals like those of Adolph Hitler.

"She’s got a to-do list, he’s got an enemies list," Walz said, contrasting Harris and Trump.

Walz said that just when he thought Trump "couldn’t get any lower," the accounts of John Kelly, the former Trump chief of staff and Marine four-star general surfaced.

"The idea that the people closest to him, four-star generals, telling us that that guy's fantasizing behind closed doors, that he wished he had Adolf Hitler’s generals. That is so damn disqualifying," he said.

Walz shifted to Trump ally billionaire Elon Musk and repeated an insult that he hurled during a campaign stop in Madison this week calling him a dips***. Walz joked that was a Minnesota term.

"I think that's a North Carolina term, too, right?" he asked. "I said that wasn't a pejorative. That's just it, standing up there as the richest man in the world. Instead of putting your money in to help people and end homelessness or end hunger or do all that you're looking for."
