PASCAGOULA, Miss. -- Sen. Trent Lott, R-Miss., says he is running for a fourth term this year, a decision that ends months of speculation on the Mississippi political scene. Lott, 64, told a hometown crowd Tuesday that he wants to continue working on federal issues related to Mississippi's recovery from Hurricane Katrina. The former Senate majority leader also has hinted that he might seek another leadership position in Washington. Lott was first elected to the U.S. House in 1972 and to the Senate in 1988.
