Republican Gov. Henry McMaster is expected to call a special session of the South Carolina legislature to redraw the state's congressional map, according to CBS News. The move follows a failed procedural vote Tuesday; a special session requires only a simple majority, clearing the threshold that blocked the bill. Said state Sen. Tom Davis, a Republican who voted against the measure: "South Carolina's maps are legally sound, our electoral position is strong, and the process being proposed remains constitutionally and practically indefensible."
