"She is part of the new generation of women in Congress who are coming into their own in a new way for a new day -- claiming their power to empower others," Mikulski said of her fellow Democrat in a statement released by the Edwards campaign.
Edwards, first elected to the 4th District in 2008, is facing a challenge in the state's April 3 primary from former Prince George's County prosecutor Glenn Ivey. Both campaigns have been relatively queit publicly but are raising the money needed to sustain an advertising campaign in the pricey Washington media market.
Though the distrtict was altered by mapmakers in Annapolis last year, it is still considered safe for Democrats. Whoever emerges from the primary will have the upper hand heading into the November general election. The district includes portions of Prince George's and Anne Arundel counties.
Edwards said she and Mikulski have worked together on several issues, including maintaining funding for federal facilities in Maryland such as Goddard Space Flight Center and NOAA. "I am proud to receive the endorsement of one of Maryland's greatest leaders," Edwards said.
