Republican officials have said South Carolina Gov. Nikki Haley will name Rep. Tim Scott to replace outgoing Sen. Jim DeMint. Haley is scheduled to name her replacement choice at noon Monday from the South Carolina Statehouse. DeMint announced about two weeks ago that he would step down from his Senate post to take a job as head of the Heritage Foundation, a conservative think tank. Scott will be the first black senator to represent South Carolina in more than 100 years.
