WASHINGTON -- U.S. Sen. Ben Cardin endorsed presumptive Democratic presidential nominee Barack Obama today saying he was confident that U.S. Sen. Barbara Mikulski and Governor
Martin O'Malley, who both threw their support to Hillary Clinton, would also rally around Obama's candidacy.
"I have no doubt that Senator Mikulski will be aggressively working on behalf of the nominee," Cardin said at a Washington press conference, where he announced his endorsement. "I am equally confident Governor O'Malley will be supporting the nominee."
