Gabbard, 34, is one of the youngest members of Congress and the first Hindu elected to Capitol Hill. She served in Iraq and with the Hawaii National Guard, and cites her military experience as the impetus for her decision to back Sanders.
"As a veteran and as a soldier I've seen firsthand the true cost of war," she said. "I think it's most important for us as we look at our choices as to who our next commander-in-chief will be ... to recognize the necessity to have a commander in chief who has foresight, who exercises good judgment."
She's the fourth current member of Congress to endorse Sanders, and the most high-profile.
