Philadelphia District Attorney Larry Krasner said that while he believes behavior at the polls has been "a little bit more aggressive," no arrests have been made in the city.

Matt Stiegler, senior adviser to the DA, said the office is "monitoring" reports of voters recording poll workers. Stiegler said the DA has gathered these from media reports, but he wouldn't say whether poll workers have reported cases of being recorded.

"Hidden camera recording of election workers and voters and poll workers, that's not normal," Stiegler said. "If that's occurring, then that's a significant escalation of what's happened in the past."

Krasner said his office has seen no indications of voter fraud. Any irregularities, however, would likely not be reported until later in the evening, he noted.

"We do not have reports of anything that looks like voter fraud...We do not expect to have it, but if it's there, we want to know about it. We don't want to hear a bunch of crazy fiction later about how things happen," he said.

"If we start to hear about it at nine o'clock after the polls are closed, you should be rightly suspicious of what you are hearing."

DA Krasner repeated his warning yesterday that consequences would be in order for lawbreakers.

"There are handcuffs, there are cells, there are courtrooms, and there are Philadelphia jurors who are definitely going to want to know why it is a person tried to erase their votes, block their votes, bully their votes, or take away their votes," he said. "We're voting in Philly. We're voting our conscience. We're voting for whoever is our favorite candidate."

A Pennsylvania judge ordered the voting hours to be extended for two hours in Cambria County, Pennsylvania, after the location experienced technical issues on Tuesday.

The polls will now close at 10 p.m., per the order, and any ballots cast after 8 p.m. will be cast by provisional ballots.

Lara Trump, the former president's daughter in law and current co-chair of the RNC, praised the ruling as "good news."

Georgia's top election official on Tuesday morning projected confidence that the critical battleground state will have the large majority of its election results available tonight, saying that election day in the state has been "smooth sailing by and large" and a "tremendous" day.

Specifically on timing, Secretary of State Brad Raffensperger said that the state's 4 million early votes as well absentee ballots will be uploaded and reported no later than one hour after the polls close, which for most locations will be 7 p.m.

"So by 8 p.m., you'll have probably 99% of all that ... so you get a good idea of what the race looks like," he said.

With regards to votes from today, Raffensperger said "before the end of the night, you'll have all of that." He noted smaller counties are aiming to have all of their results in by 10/1030 p.m. "at the latest."

Notably, Raffensperger was also asked about bomb threats made Tuesday, which he said were "of Russian origin."

"We identified the source and it was from Russia," he said, after hedging briefly on the source.

"They're up to mischief it seems," he said of Russia: "They're not our friends anyone who thinks they are hasn't been reading the newspaper."

Raffensperger said he thinks they will pass 1 million votes today, and said they are ready for any litigation to come their way.

"We're gonna follow the law, follow the Constitution, and report the results accurately."

A polling location in Washington, D.C., was briefly closed for less than an hour Tuesday morning after "officers were notified of a suspicious package," police said.

The city's Explosive Ordnance Disposal responded to the scene near the Martin Luther King Jr. Memorial Library and quickly determined the item posed no threat.

The polling site has since reopened.
