South Carolina's race for governor turned into a family pile-on when U.S. Rep. Joe Wilson — the father of GOP candidate Alan Wilson — tore into fellow GOP congresswoman and gubernatorial hopeful Nancy Mace, accusing her of showboating in Washington.

She joins a crowded Republican primary field that includes a rival candidate she has already clashed with sharply this year.

The Charleston-area congresswoman was once a moderate Republican, but has more recently presented herself as a loyal supporter of President Trump.
