Democrats appear on the brink of taking control of the U.S. Senate with Raphael Warnock the projected winner over Republican Sen. Kelly Loeffler and Democrat Jon Ossoff leading Republican Sen. David Perdue in Georgia’s two Senate runoff elections.

Around 2 a.m. ET Wednesday, the Associated Press projected Warnock the winner over Loeffler after the Atlanta pastor built his statewide lead to more than 46,500 votes.

Warnock made history with his election win, becoming the first Black Democrat elected as a U.S. senator from a state in the South and only the 11th Black senator in the history of the nation. He becomes the first Democrat to win a U.S. Senate race in Georgia in 20 years, reports USAtoday.

“To everyone out there struggling today, whether you voted for me or not, know this,” Warnock said as he declared victory in a video from his home. “I hear you, I see you, and every day I’m in the United States Senate, I will fight for you. I will fight for your family.”

Trailing much of the night, Ossoff surged ahead of Perdue by more than 8,500 votes after batches of votes from Democrat-heavy DeKalb County were released. Most uncounted votes remain in Democratic strongholds in the metro Atlanta area.

“When all the votes are counted we fully expect that Jon Ossoff will have won this election to represent Georgia in the United States Senate,” Ossoff campaign manager Ellen Foster said in a statement. “The outstanding vote is squarely in parts of the state where Jon’s performance has been dominant.”

The Perdue campaign was not ready to concede.

In a statement, the Perdue campaign said the race — as they expected – is “an exceptionally close election that will require time and transparency to be certain the results are fair and accurate and the voices of Georgians are heard.

“We will mobilize every available resource and exhaust every legal recourse to ensure all legally cast ballots are properly counted. We believe in the end, Senator Perdue will be victorious.”

Gabriel Sterling, Georgia voting system implementation manager, said he expects most ballots to be counted by Wednesday but for final counts not until Friday.
