Chester Trent Lott Sr. (born October 9, 1941) is an American author and former politician. A former United States Senator from Mississippi, Lott served in numerous leadership positions in both the United States House of Representatives and the Senate. He entered Congress as one of the first of a wave of Republicans winning seats in Southern states that had been solidly Democratic. Later in his career, he became Senate Majority Leader, and, alternately, Senate Minority Leader. In 2003, he stepped down from the position after controversy due to his praising of senator Strom Thurmond's 1948 segregationist Dixiecrat presidential bid.
