"It’s time for Democrats to come together to focus on supporting the best candidate for victory in November. That’s why I am joining many of my colleagues to endorse, my friend, Joe Biden for President," Costa said in a statement.
Costa said Biden is "clearly the most qualified candidate," noting the candidate's "extensive" background in domestic and foreign policy.
"Above all else, we must have a person that has the empathy and compassion to heal the wounds and bring the divisions in our country together again," Costa said. "Vice President Joe Biden best represents the values that offer the hope and promise for America’s future."
