(CNN) Florida Democratic Rep. Val Demings on Thursday endorsed former Vice President Joe Biden for president, saying Biden "has been there in the trenches fighting for those things that are important to the American people."

"What I do know is America is always at its best when people have the opportunity to succeed," Demings told CNN's John Berman on "New Day." "And we have leaders in place who understand that. That's why I'm so proud this morning to endorse Joe Biden for the next president of the United States."

Demings is one of two dozen members of the Congressional Black Caucus to endorse Biden, which is by far the most endorsements from that caucus for any presidential candidate. Her announcement comes after Biden's big wins on Super Tuesday and adds to his considerable support among members of Congress -- including Florida Democratic Rep. Ted Deutch, who backed Biden just one day before, and Rep. Anthony Brown of Maryland who announced his endorsement Thursday morning.

Demings did not rule out being Biden's running mate if she was asked and said she was "humbled" that her name has been raised as a potential add to the Democratic ticket.

Demings represents Florida's 10th Congressional District, and was Orlando's first female chief of police. She serves on the House Permanent Select Committee on Intelligence, the House Committee on the Judiciary and the House Committee on Homeland Security.
