South Carolina Gov. Nikki Haley (R) plans to announce at noon ET her choice of successor for retiring Republican Sen. Jim DeMint, her spokesman tells The Associated Press.
DeMint, a Tea Party favorite, announced earlier this month that he's stepping down to become president of the conservative Heritage Foundation.
As The Hill writes: "South Carolina Republican Reps. Tim Scott and Trey Gowdy have regularly been mentioned as possible replacements for DeMint. ... Former South Carolina Attorney General Henry McMaster (R) and Catherine Templeton, who heads the state's Department of Health and Environmental Control, are also on Haley's shortlist."
There's also been talk that former South Carolina first lady Jenny Sanford might be Haley's choice.
And then there's the not-so-serious speculation about Stephen Colbert.
