Maryland US Rep. Dutch Ruppersberger endorses David Trone while colleagues back Angela Alsobrooks in Senate race

U.S. Rep. C.A. Dutch Ruppersberger said Monday he would back U.S. Rep. David Trone in Maryland’s Senate race next year — lending Trone the support of one of the state’s longest-tenured congressmen while three others in the mostly Democratic eight-member delegation have endorsed Angela Alsobrooks. Ruppersberger, a former Baltimore County executive who was first elected to the House in 2002, is the first major Democratic official in the Baltimore area — or across the state — to endorse Trone in the May 14 primary.
