(Hawaii News Now) - The nation's 113th Congress began today with the swearing in ceremonies of two of Hawaii's four delegates. Vice President Joe Biden delivered the oath that made Mazie Hirono Hawaii's 7th U.S. Senator while House Speaker John Boehner swore in Gabbard as Hawaii's 13th U.S. Representative. In this new Congress, Hawaii's delegation goes from being one of the most senior to one of the greenest. But Hirono and Gabbard vowed to work closely with their colleagues to protect Hawaii's interests. "We are going to build on the foundation laid by our two senators -- Senator Inouye and Senator Akaka," Hirono said. "We do this as a delegation, how we've always done it, working very closely and together in a united way and do what's best for Hawaii." Meanwhile, on her first day on the job, Gabbard was labeled as one of the "rising stars" of the Democratic party on CNN's "The Situation Room". "I'm just grateful. The overwhelming feeling I'm feeling today is grateful to the people of Hawaii for placing their trust and confidence in me," Gabbard said. Hirono was elected to succeed longtime Sen. Daniel Akaka. She joins U.S. Sen. Brian Schatz, who was appointed one week ago to replace the late Sen. Daniel Inouye. Gabbard, who was elected to fill Hirono's seat, will join incumbent Colleen Hanabusa in the House. Copyright 2013 Hawaii News Now. All rights reserved.
