South Carolina Gov. Nikki Haley (R) has narrowed her list of potential Senate appointees down to five -- including the state's former first lady Jenny Sanford. A person close to the process confirms that the five names under "active consideration" are Sanford, Rep. Tim Scott, Rep. Trey Gowdy, former state attorney general Henry McMaster and Catherine Templeton, the director of the state Department of Health and Environmental Control.
