U.S. Sen. Deb Fischer has been named to Senate committees dealing with the military, environment and small business.

The Nebraska Republican announced her assignments Thursday, the same day she was sworn as Nebraska’s newest U.S. senator.

Fischer was elected in November, defeating Democrat and former U.S. Sen. Bob Kerrey to replace Sen. Ben Nelson.

Fischer will serve on five Senate committees: Armed Services; Commerce, Science, and Transportation; Environment and Public Works; Small Business; and Indian Affairs.

Fischer says she is committed to working with Republicans and Democrats “to restore America’s fidelity to her constitutional principles.”
