South Carolina Gov. Nikki R. Haley is set to appoint Republican Rep. Tim Scott to succeed Sen. Jim DeMint, R-S.C., according to several news reports. The official announcement is expected to come at noon Monday.

Scott would immediately be up for re-election in 2014 to finish the rest of DeMint’s term, which expires in 2017.

DeMint announced plans to resign from Congress a week and a half ago to take the reigns of The Heritage Foundation, a conservative think tank.
