Maryland Lt. Gov. Anthony G. Brown (D) picked up an endorsement for his gubernatorial bid Thursday from a group representing 1,800 officers in state police agencies, including the Maryland State Police.

The State Law Enforcement Officers Labor Alliance (SLEOLA) cited Brown’s tenure in office and public-safety proposals as a candidate, as well as his military service, in its decision to back him for governor.

“As a 30-year military veteran who’s served a tour of duty in Iraq, Anthony understands the sacrifices Maryland police officers make and respects our work keeping Maryland safe,” the group’s president, Jimmy Dulay, said in a statement.

Brown faces Attorney General Douglas F. Gansler and Del. Heather R. Mizeur (Montgomery) in the June 24 Democratic primary.

SLEOLA draws its membership from several state police agencies, including the Maryland State Police, the Maryland Capitol Police, the Natural Resources Police and State Fire Marshals, among others.
