Democratic newcomer Lucy McBath, who became an anti-gun violence advocate following the fatal shooting of her son Jordan Davis in 2012, has won the House seat in Georgia’s 6th congressional district after Republican Rep. Karen Handel conceded the race Thursday morning, per local outlet Channel 2 Action News.

The big picture: McBath's win, which gained her the seat Handel won over Jon Ossoff last year, was sealed just hours after another mass shooting killed at least 12 at a country music bar in Thousand Oaks, Calif. Everytown for Gun Safety had invested $1.35 million in McBath's congressional bid this summer as its first major investment in the midterms election cycle.
