LL’s on the scene at the Kennedy Rec Center in Shaw, where Ward 2 Councilmember Jack Evans is holding his re-election kickoff party.

In the company of council Chairman Vincent C. Gray and Mayor Adrian M. Fenty, Evans announced minutes ago he’s throwing his support behind Barack Obama for the Democratic presidential nomination.

Evans had been a longtime Hillary Clinton supporter, co-chairing her campaign in the District. Earlier this month, he’d been elected by local Democrats to serve as an at-large delegate pledged to Clinton.

Asked to explain his move, Evans cited “just the momentum that was going behind it.” He says he left a message with the Clinton campaign about the decision but was not able to speak with the senator before making the announcement today.

“It’s important for the city that we have a good relationship with the next president,” Evans says.
