Longtime Ward 2 D.C. Council member Jack Evans will announce his run for mayor June 8, NBC 4 reported Wednesday.

Evans, the longest-serving council member and finance committee chair, had floated that he would likely run for mayor this year, and now will join council members and fellow Democrats Muriel Bowser and Tommy Wells in the 2014 contest.

GW alumnus and incumbent Mayor Vincent Gray, whose 2010 campaign is under federal investigation, has not announced his candidacy.

Evans, whose folksy demeanor is popular with his constituents and donors, has held his seat in the ward that includes Foggy Bottom, Georgetown and Dupont Circle since 1991. He coasted to victory last fall after he was unopposed in the council election.

The 59-year-old has advocated for economic development boosters like the construction of Nationals Park and tax breaks for tech business.

Evans last ran for mayor in 1998, when he lost badly to former Mayor Anthony Williams. Evans will make his official announcement June 8 at Le Diplomate restaurant in Logan Circle at 10 a.m.
