Florida Republican David Jolly has been sworn in as the newest member of the House.
Speaker John Boehner administered the oath on Thursday. It was two days after Jolly edged out Democrat Alex Sink in a special election that Republicans cast as a referendum on the president and his unpopular health care law. The Tampa-area district had been considered a tossup.
Jolly fills the open seat that had been held by Republican C.W. Bill Young for decades. Young died in October.
The 41-year-old Jolly has a lot of experience in Washington, first as an aide to Young and then as a lobbyist.
Republicans now hold 233 seats in the House to the Democrats' 199. There are three vacancies.
