One name notably not on the list: Rep. Mick Mulvaney (R-S.C.), who said last week he thought he was in the mix and sources say has been considering a Senate run.

The source said Haley's order of preference of the candidates is "still fluid."

CNN first reported the list in a story Haley refuted during a Tuesday afternoon press conference, according to local reports. She said only her husband knows who's on the list.

Scott has been the most buzzed-about name, and sources told The Hill last week that he is DeMint's preferred replacement. Sanford and McMaster were both major backers of Haley's gubernatorial run.
