Maryland Lt. Gov. Anthony G. Brown (D) picked up an endorsement of his gubernatorial bid Saturday from former governor Harry Hughes (D), who became the third person who has held the position to announce support for Brown.

Hughes, who served from 1979 to 1987, cited Brown’s record on the environment and his commitment to creating jobs in making his decision.

“I’m firmly behind Anthony’s candidacy and he’s a clear best choice for our environment and our middle class,” Hughes said in a statement.

Brown faces Attorney General Douglas F. Gansler and Del. Heather R. Mizeur in the June 24 Democratic primary for governor.

Brown has previously won endorsements from Gov. Martin O’Malley (D) and former governor Parris N. Glendening (D), who served from 1995 to 2003.

He is also supported by both presiding officers of the state legislature, both of the state’s U.S. senators and five of the state’s U.S. House members, including Minority Whip Steny H. Hoyer (D-Md.).

Gansler has sought to turn the support Brown has attracted into a disadvantage, arguing that he is beholden to “the Democratic establishment.” Gansler argues he is better positioned to shake up the status quo in Annapolis.
