Election security updates: Trump baselessly asserts cheating

Law enforcement officials say they're prepared to deal with unrest on Election Day, but expect the threat to continue in the days that follow.

Election workers across the country are being bombarded with threats and law enforcement agencies nationwide are dedicating "substantial resources" to ensure public safety during the election, a new threat assessment obtained by ABC News says.

"It is more likely that in the aftermath of the election results and the counting of the Electoral College votes, that individuals who believe that the election was rigged, stolen, or unfairly decided could decide to conduct lone offender or lone wolf attacks in response," said Javed Ali, the former senior counterterrorism coordinator at the National Security Council and now an associate professor at the University of Michigan's Gerald R. Ford School of Public Policy.

The FBI said in a statement that they are aware of bomb threats in "several states" and "many of which appear to originate from Russian email domains."

"None of the threats have been determined to be credible thus far," the FBI said.

Earlier, Georgia Secretary of State Brad Raffensperger said a series of bomb threats in Fulton County appeared to come from Russia, but did not explain further.

"As always, we urge the public to remain vigilant and report suspicious activity to state or local law enforcement, or submit tips to the FBI at 1-800-CALL-FBI (1-800-225-5324) or online at tips.fbi.gov," the agency said.

Representatives from the nation's largest voter help hotline echoed what ABC News heard from state election officials in the battlegrounds: So far, so good. There have been no major disruptions or other issues beyond isolated, garden-variety episodes, the hotline said.

The Election Protection Hotline (1-866-OUR-VOTE) is run by the nonpartisan Lawyers Committee for Civil Rights Under Law and is staffed by 4,776 volunteer lawyers across 50 states. ABC News has profiled and embedded with this service in previous elections.

As of noon ET, the hotline has received 6,000 calls from voters. The majority of the calls have come in from Pennsylvania, North Carolina, Florida and Michigan.

Most of those were reporting frustration with long lines, delays in polling place opening, or difficulty using electronic voting machines.

So far, organizers have seen no widespread episodes of violence or intimidation.

The longest lines tracked by hotline are in Florida, Michigan and Pennsylvania, particularly near college campuses. Legal teams are seeking voting extensions at select polling places in Georgia, Illinois and Kentucky, where there were delays in opening this morning -- but nothing out of the ordinary.

At a press conference, a Maricopa County official debunked misinformation circulating on X about voting centers in the county being shut down due to issues with the printers.

"There have been no vote centers that have been shut down," said Maricopa County Supervisor Bill Gates.

Earlier today, Tyler Bowyer, an executive with Turning Point USA who was charged in the Arizona 2020 fake elector case, posted on X that the right-wing group was sending buses to move people to functioning voting centers in Maricopa County.

"We have reports of multiple vote centers with ink issues in Maricopa County," Bowyer posted.

Gates said the printers are being serviced as usual. "We are out there going ahead and servicing the printers as we normally would," the Maricopa County official said in response to Bowyer's tweets.

The Maricopa County supervisor said that as of Monday, more than 1.5 million voters in the county had returned early ballots. About 70- 75% of those votes will be reported in the first batch of results at 8 p.m., he said.

Gates also said that if voters get in line at 7 p.m., they will have an opportunity to vote no matter how long lines are.

"Stay in line and go ahead and vote," he said.
