"The Colbert family has always been a strong advocate for all the people of South Carolina," Lewis added. I have visited the First District and know they need a powerful voice in Washington; Elizabeth can be that voice. I know she will be a hard working and dedicated Member of Congress who speaks up and speaks out for the people she serves."
