Nashville (WVLT/AP) -- Tennessee Senator Lamar Alexander says he will make a bid for the number three post among senate republicans.
This comes after Mississippi's Trent Lott announced he planned to resign.
Lott beat Alexander last year by just one vote to become the minority whip.
Senator Alexander said he plans to support Senator Jon Kyl of Arizona to replace Lott, and that he'll seek to fill Kyl's position as Republican conference chairman.
Alexander is 67 and is up for re-election next year.
He was first elected to the Senate in 2002 and was previously a two-term governor, U.S. education secretary, University of Tennessee President, and two-time presidential candidate.
