Election security: Officials say 2024 election saw only 'minor' disruptive activities

Isolated voting delays at several polling places around the country have prompted local officials to seek voting-hour extensions, which typically happens during every election cycle.

Among those sites whose hours have been extended are the following:

Cobb County, Georgia (20 minutes)
A judge granted Cobb County's request to keep two polling locations open an additional 20 minutes until 7:20 p.m. ET because of delayed openings due to "equipment issues," the county said in a statement.

Gwinnett County, Georgia (58 minutes)
A judge granted Gwinnett County's request to keep two polling locations open for an additional 58 minutes until 7:58 p.m. ET due to a security threat prompted a temporary evacuation earlier today.

Luzerne County, Pennsylvania (90 minutes)
A judge granted Luzerne County's request to extend voting for 90 minutes until 9:30 p.m. ET after one polling location in Laflin opened late.

Cambria County, Pennsylvania (2 hours)
A Pennsylvania judge ordered voting hours to be extended for two hours in Cambria County after scanners there were not able to read ballot markings and tabulate votes.

Wilson County and Burke County, North Carolina (30 minutes)
The North Carolina State Board of Elections approved extending the voting hours by 30 minutes at two precincts after both opened late this morning due to technical issues.

Fulton County, Georgia (various)
Due to threats today that required brief evacuation of five different polling locations, the Superior Court of Fulton County issued a ruling this afternoon allowing extension of voting hours at the Etris Darnell Community Center until 7:45 p.m. ET, C.H. Gullatt Elementary School until 7:15 p.m. ET, Southwest Arts Center until 7:43 p.m. ET, Northwood Elementary School until 7:45 p.m. ET and Lake Forest Elementary School until 7:10 p.m. ET

A federal judge has rejected an RNC lawsuit seeking to block some Georgia counties from accepting ballots that were hand-delivered over the weekend and Monday, according to Marc Elias, a lawyer working for Vice President Kamala Harris' campaign.

Judge R. Stan Baker -- who was appointed by former President Donald Trump -- said the lawsuit from Republicans "does not withstand even the most basic level of statutory review and reading comprehension," per Elias.

Republicans had claimed that the seven Georgia counties that were accepting hand-delivered mail-in ballots after the early voting period were violating the law.

The North Carolina State Board of Elections approved extending the voting hours at two precincts after both opened late this morning due to technical issues.

The Gardners School precinct in Wilson County and Pilot Mountain Precinct in Burke County will be open for 30 additional minutes.

The extended hours in the two countries will not impact the timing of results for the rest of the state, authorities said.

The U.S. Capitol Police said they arrested a man who smelled like fuel and had a flare gun and a torch while going through screening at the Capitol's visitor center.

Capitol Police Chief Tom Manger told reporters that officers found a flare gun, lighter, and torch lighter in the man's jacket and two bottles that appeared to contain some sort of accelerant, possibly gasoline.

The suspect had papers he told officers he intended to deliver to Congress. Investigators are working to determine what his intentions were. Capitol Police said they're unclear if he wanted to set himself on fire or his items.

The officers were tipped off because the suspect had "heavier clothing than was warranted for a day like today," Manger said, as afternoon temperatures in D.C. were around 75 degrees.

The visitor center has been closed for tours while police investigate.
