Baltimore State's Attorney Marilyn J. Mosby will endorse Rep. Donna F. Edwards' bid for Senate, the campaign said Monday.
The endorsement, which the campaign said in a news advisory will take place on Tuesday in Baltimore, would represent the highest-profile endorsement she has received from an elected African American official to date. Most of the state's highest-profile black leaders have backed rival Rep. Chris Van Hollen.
Mosby is prosecuting the six police officers involved in the death of Freddie Gray a year ago. Her husband, first-term City Councilman Nick J. Mosby, had mounted a campaign for mayor but dropped out of the race last week.
