Former Montana Gov. Brian Schweitzer says he won't run for U.S. Senate after Sen. John Walsh dropped his election campaign Thursday.
Schweitzer was mentioned as a potential contender even before Walsh's announcement.
But the Democrat already rejected a run earlier in the year when he said he wasn't interested in the seat that opened when six-term Sen. Max Baucus was named U.S. Ambassador to China.
Schweitzer announced that he wouldn't run on Twitter and confirmed it to The Associated Press. He said in a Facebook post that he was flattered his name was considered, and that he'll support whoever emerges as the candidate.
Earlier Thursday, Walsh said in a statement to supporters that he is leaving the race but will keep the seat he was appointed to until his term ends in January 2015.
