Democrat Maggie Hassan has been sworn in as a U.S. senator, becoming only the second woman to serve as a state's governor and senator in American history.
Hassan, a two-term governor, resigned at midnight Monday. She was sworn in by Vice President Joe Biden in the Senate Chamber in Washington at noon Tuesday, using the Bible that she received from her mother as a child.
In New Hampshire, Hassan handed over the reins to Republican Senate President Chuck Morse. He is serving as governor until Gov.-elect Chris Sununu, also a Republican, is inaugurated Thursday.
