Rep. Ron Barber, D-Ariz., was sworn in to office on Tuesday after winning a special election to replace his former boss, Gabrielle Giffords, who resigned earlier in the year.
Barber is only the latest member of the House of Representatives to take a seat long after the 112th Congress began. The new members were elected after their their predecessors resigned in scandal, to take new jobs, or for other reasons.
There are also two vacancies in the House. One is the result of the resignation of Rep. Jay Inslee, D-Wash., who stepped down to focus on his run for governor. The other is the result of the death of Rep. Donald Payne, D-N.J., earlier this year.
Below are the newest members of the House, according to the House Press Gallery website.
