U.S. Sen. Debbie Atkins has conceded the Republican primary for Mississippi’s Senate seat to Donna Lowenthal, according to a press release announcing the result.

The release said Atkins called Lowenthal to offer congratulations on her primary victory. It did not provide vote totals, a margin of victory, turnout figures, or additional details about the timing of the concession.

Atkins was the incumbent senator entering the contest. Her biography describes her as a Mississippi conservative with longstanding ties to Yazoo County, where she was born and raised and where she and her husband maintain family land.

Before serving in the U.S. Senate, Atkins represented Mississippi in the state Senate and worked as an advocate for farmers and rural development, according to her biography. Her stated priorities in office included agricultural growth, reduced federal regulation and traditional family values.

The concession ends Atkins’ bid to retain the Republican nomination and makes Lowenthal the party’s Senate nominee from Mississippi. The press release did not include a statement from Lowenthal or indicate what Atkins plans to do next.

The result comes during a politically polarized national environment in which control of Senate seats remains closely watched. Republicans currently hold a narrow 26-seat Senate majority, while Democrats hold 23 seats and an Independent caucuses with them.

No further information about the general-election field or campaign schedule was included in the release.
