D.C. Councilmember Tommy Wells is set to formally kick off his campaign for mayor.
Wells will announce his candidacy on Saturday at a busy intersection in the ward he represents.
Wells formed an exploratory committee in February. He'll be the second candidate to formally enter the race, following Councilmember Muriel Bowser, who launched her campaign in March.
Mayor Vincent Gray has not said whether he is seeking re-election. Gray's 2010 campaign is the subject of a federal investigation, and three former campaign aides have pleaded guilty to felonies.
Wells is a 56-year-old Democrat who's served on the D.C. Council since 2007. He'll have to give up his council seat to run for mayor. He says in a statement that he wants to “clean up corruption in city government.”
