Mfume is the latest prominent black leader in the state to announce support for Cardin, who lost Baltimore city and Prince George's County in his 2006 primary against Mfume. Cardin secured an endorsement from Prince George's County Executive Rushern Baker earlier this week, and already has the backing of Baltimore Mayor Stephanie Rawlings-Blake and Lt. Gov. Anthony Brown.
“Whether he’s fighting to create jobs, supporting our small businesses, protecting retirement security, expanding health care coverage, keeping our air and water clean, or defending civil rights, Ben works around the gridlock and gets the job done," Mfume said in a statement released by the Cardin campaign.
The endorsement comes a day after a Prince George's County legislator, state Sen. C. Anthony Muse, announced that he will mount a challenge to Cardin in the April 3 primary.
