John Kerry is now the nation's 68th secretary of State.
Kerry was sworn in Friday afternoon at a private ceremony on Capitol Hill by Supreme Court Justice Elena Kagan. He is expected to have a public swearing-in ceremony sometime next week, and his arrival at the State Department at 9 a.m. on Monday will be televised.
Kerry is the first chairman of the Senate Foreign Services Committee to become secretary of State in more than a century, according to his State Department biography. He was sworn in in front of a bust of former secretary of State and United Nations champion Cordell Hull, CNN reported, and received his Senate floor chair as a parting gift from his staff.
