Kingston, an 11-term GOP House veteran, said he was considering seeking the seat. Kingston, 57, said his knowledge of defense and agriculture, important issues in Georgia, would help him in a race.
Among other potential Republican candidates is four-term Rep. Tom Price from a district north of Atlanta.
Other possible Republican candidates are two other House members — Reps. Paul Broun and Phil Gingrey, both physicians.

Pizza mogul Herman Cain, the failed presidential candidate in 2012 and a tea party favorite, said he would not seek the seat but rather focus on his radio show.
