Georgia Rep. Buddy Carter became the first high-profile Republican to announce a challenge to vulnerable Democratic Sen. Jon Ossoff.

U.S. Rep. Buddy Carter on Thursday became the first Republican to jump into the race to challenge Democratic U.S. Sen. Jon Ossoff in 2026, as other hopefuls maneuver following Gov. Brian Kemp's announcement that he won't seek the seat.

Gov. Brian Kemp's decision not to run has some Republicans concerned that Rep. Marjorie Taylor Greene might decide to jump in and, in their view, jeopardize the GOP's chances.
