Ballot-printing issues cause long lines in Arizona county
There are "residual issues" including long lines at the polls in Apache County, Arizona, after the machines that print ballots "did not work as planned" Tuesday morning, state officials said.

The countywide issue was fixed earlier in the day and most sites in the county are "up and running well but as we understand at this moment, there are still some residual issues out in Apache County," Arizona Secretary of State Adrian Fontes said. "We're doing our best to work with county election officials there to see if we can resolve any of the remaining problems."
Rita Vaughan, the elections director for Apache County, told ABC News that "all polling places have remained open and voting has continued all day for registered voters who want to cast their ballots."

Milwaukee will rerun 31K absentee ballots, delaying count
Milwaukee will have to retabulate approximately 31,000 absentee ballots after a human error at the city's central ballot processing location, likely delaying the city's final results by hours.
A door to several tabulators was not properly sealed, according to Jeff Fleming of the Milwaukee mayor's office.
"The people operating the machines along both walls -- the 13 machines -- are being reset to zero," Fleming said. "They will rerun all the ballots that they previously ran after it has been reset."
Election workers process ballots for the 2024 General Election, on Nov. 5, 2024, in Milwaukee.

Milwaukee received a total of 106,000 absentee ballots, which are processed at the city's Baird Convention Center. The city cannot report the results of the absentee ballots until every ballot is counted, per Wisconsin law.
"We're guessing, you know, one hour, two hours, three hours, four. We just don't know at this stage," Fleming said about the delay.
Fleming said the issue was "human error" that he blamed on "senior election staff."
"We want to make sure everybody understands that our goal here in this room is to be absolutely accurate beyond any question, and to do that, we're going to rerun the balance," Fleming said.
The Milwaukee Election Commission said that the doors to the tabulators were not “fully in place,” forcing a restart of the process.
“The City of Milwaukee has no doubt regarding the integrity of the election," the commission said in a statement. "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."

Trump baselessly claims 'massive CHEATING' in Philadelphia
Former President Donald Trump falsely claimed on social media Tuesday afternoon that there is "a lot of talk about massive CHEATING" in Philadelphia -- despite no evidence to support those claims.
Philadelphia District Attorney Larry Krasner said Tuesday that they "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."
"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," Krasner said.
The post comes as Trump has for days basely accused the key battleground state of cheating.
"If Donald J. Trump has any facts to support his wild allegations, we want them now. Right now," Krasner said. "We are not holding our breath."
In a separate statement, the Pennsylvania Department of State said, "Pennsylvania counties, including Philadelphia, are running a safe and secure election."

Bomb threats to Georgia polling locations were in Cyrillic letters: Official
Russia-linked bomb threats to Georgia polling locations "came through the internet" and were in Cyrillic letters, according to Georgia Secretary of State Brad Raffensperger.
"So you know it came from Russia, so that helped us save some time on that one," Raffensperger said at a press briefing.
Two polling locations in Fulton County were evacuated briefly Tuesday morning after officials received five bomb threats the county later deemed to be non-credible, Raffensperger said.
Raffensperger also noted Tuesday evening that "just over 800,000" voters had cast their ballot in-person on Tuesday. He said he expects that by the end of the night "north of 1.1 million" votes will be cast.
