Republican John Kennedy won his Louisiana Senate race against Public Service Commissioner Foster Campbell Saturday night. Kennedy, who served as Louisiana's treasurer, will replace retiring Sen. David Vitter (D), increasing the GOP's Senate majority to 52 seats.

Earlier this week, President-elect Donald Trump campaigned for Kennedy, telling voters, "We need John in Washington."

The Republican National Committee is thrilled for yet another victory.

"Congratulations to Senator-elect John Kennedy on winning this race and joining our Republican majority in the Senate!" said RNC Co-Chair Sharon Day in a statement. "This win caps a year of historic Republican wins up and down the ballot, and with 52 seats in the U.S. Senate, we are excited for Republicans to confirm a conservative Supreme Court justice and begin working with President-elect Trump to pass an agenda of change for the American people. Whether it's winning the White House, Congress, or state-level races, Republicans have much to celebrate this year, and the RNC is ready to get to work to Make America Great Again."
