Election officials push back on Trump claims of irregularities

Philadelphia city commissioner Seth Bluestein, a Republican, rebuked former President Donald Trump's claim earlier Tuesday that "cheating" took place in the city, emphasizing that the city worked closely with the Republican National Committee "in real time" to field complaints and that "there is no evidence whatsoever of massive cheating."

"If anybody has evidence of widespread cheating, please send it in, because we'd like to see it, and I guarantee you there won't be any," Bluestein said.

"Just think about everyone who stood up for democracy today," commission chair Omar Sabir, a Democrat, said -- his voice choked with emotion -- as he thanked election workers.

In Detroit, Michigan Secretary of State Jocelyn Benson called out Trump for sowing "seeds of doubt" about the election.

"If there are either candidates or other bad actors, or even foreign bad actors who try to continue to inject confusion or fear or sow seeds of doubt about the sanctity of their elections in the hours and days ahead, we'll be there to speak the truth and ensure people know what is actually happening," Benson said during a press conference at Detroit's Ford Field.

Milwaukee calls in reinforcements to help process ballots

Milwaukee has called in reinforcements from other parts of the city government to help process ballots as it works through a backlog of 31,000 absentee ballots.

Ballots are stacked on a table at the central count in Baird center, during the 2024 U.S. presidential election, in Milwaukee, Wis., Nov. 5, 2024.

Approximately 40 city employees -- including firefighters, health employees, IT experts and librarians -- are assisting with the count of absentee ballots, according to a city official.

The absentee ballots are being retabulated after a door to several tabulators was not properly sealed due to human error, the Milwaukee mayor's office said.

As the counting continues, some Republicans have descended on the Baird Convention Center to ask about how this mistake happened.

"This seems like a real mess," Sen. Ron Johnson said.

Johnson said he showed up at the polling location to "ask questions" and "restore confidence" in the results. He said he believes the city was unprepared for the election.

Johnson was joined by GOP Chair Brian Schimming, who summed up the incident in a few words: "You had one job."

The Milwaukee Election Commission earlier said that the city "has no doubt regarding the integrity of the election."

"However, in order to eliminate any doubt to be fully transparent, the MEC has decided to start the tabulation process over for all ballots at Central Count. This decision was made in consultation with both Republican and Democratic officials," the commission said.

There were 1.22 million voters on Election Day voters, a record in the state, Raffensperger said.

Asked whether the bomb threats had any impact on voter turnout or the performance of election officials, Raffensperger said, "None. We worked through it. Battle-tested."

"That just shows you the resilience of our system and our people," he said.

The state also had a record 4 million early voters, according to Raffensperger.

Judge extends Pa. county voting hours after bomb threat

A Pennsylvania judge granted a petition in Clearfield County to extend voting until 9 p.m. after a bomb threat targeted an administrative building where votes were being counted.

The judge made an oral ruling and a written petition will be filed in the morning, a spokesperson said.

Pennsylvania Gov. Josh Shapiro confirmed there was a series of bomb threats in the state and said his office is collaborating with local, state, and federal law enforcement in response to the threats.

"Thus far, there is no credible threat to the Commonwealth," he said.
