Republican U.S. Sen. David Vitter will be a candidate in Louisiana's 2015 governor's race.
Vitter announced his plans in an email to supporters on Tuesday, saying "I believe that as our next governor, I can have a bigger impact addressing the unique challenges and opportunities we face in Louisiana."
The Associated Press obtained the announcement from Vitter's staff.
Vitter's announcement ends months of speculation. His decision is expected to influence which other potential candidates enter the race.
