Katie Britt has secured the GOP nomination for an Alabama U.S. Senate seat, ousting U.S. Rep. Mo Brooks in a runoff, according to a race call by The Associated Press.

In last month's primary, neither candidate got the majority of the vote required to win outright and avoid a runoff. Britt received 44.8% of the vote to Brooks' 29.1%.
