Election 2024: Donald Trump selects his campaign manager as incoming White House chief of staff

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.

ABC News is projecting that Trump has won West Virginia's four electoral votes. More importantly, ABC News is also projecting that Republican Jim Justice has won the Senate race there and will succeed Democrat-turned-independent Joe Manchin.

That's Republicans' first flip of the night in the Senate, which means Democrats are already down to 50 seats (and could lose the majority with a Trump/Vance win) even if they hold all their other seats tonight. That's how difficult it was going to be for them.

With ABC News projecting a win for Justice in the West Virginia Senate race, we can safely say that Jim Justice's English Bulldog, Babydog, is heading to D.C. While she's not a newcomer to the political stage, having featured in Justice's appearance at the DNC, this will be her biggest move yet.

West Virginia Gov. Jim Justice took the stage with his dog, Babydog, who trotted out and took a cushioned seat to the governor's right.

It's always a big moment on election night when massive Miami-Dade County in Florida reports its first batch of votes - and it just did. With 70% of the expected vote counted in the county, Trump is at 55% and Harris is at 44%. If that holds, it would be another huge shift rightward for the heavily Hispanic county. It voted for Biden by 7 points in 2020.
