Election 2024: Kamala Harris urges importance of accepting election results

There are 18 states that have never had a female governor. Tonight, two Democratic female candidates could break their state's dry spell: Jennifer McCormick in Indiana and Crystal Quade in Missouri. But because both these states lean red, it remains unlikely.

Currently, more women are serving as governor simultaneously than ever before. It's just 12.

Additional non-credible bomb threats were sent to polling locations in the Atlanta area, according to Georgia Secretary of State Brad Raffensperger, as a dozen counties remain open late due to threat-related evacuations earlier in the day.

"I know that in Atlanta, they just got a whole bunch of bomb threats coming through," Raffensperger said at a press briefing Tuesday evening. "All the precincts are staying open and they're just sending dogs around to sweep it to make sure they're safe."

"Best we can tell these would probably be coming from the same source," he added, referring to his earlier claim that Russia was behind the threats.

Raffensperger said 12 counties across the state are remaining open late due to threats to polling places: six in Dekalb, five in Fulton and one in Gwinnett.

Three additional locations will be open late due to "normal causes," he said, for 15 total counties statewide staying open late.

A poll observer identified the error that resulted in Milwaukee officials' decision to rerun approximately 31,000 absentee ballots earlier today.

Milwaukee's top election official said that the city's election results will likely be reported in the "early morning hours" after an error at a central processing location forced a retabulation of 31,00 ballots.

Milwaukee Election Commission Director Paulina Gutierrez said the error was identified by a poll observer -- a member of the public who watches election officials for the sake of transparency.

The Trump criticized Milwaukee election officials for the error.

"This is an unacceptable example of incompetent election administration in a key swing state: voters deserve better and we are unambiguously calling on Milwaukee's officials to do their jobs and count ballots quickly and effectively," RNC Chairman Michael Whatley and Co-Chair Lara Trump said in a statement.

"It's a human error," Gutierrez said. "That is the point of central county elections, is that it's transparent, and the observers brought it to our attention."

It's now 7:30 p.m. Eastern, and all polling places in North Carolina, Ohio and West Virginia have closed.
