House, beginning in 1956. He served as House Majority Leader from 1961 to 1962. In his first run for Congress in
1962, he won the GOP nomination in a June but lost the general election to incumbent

1968. He served three terms before being ousted in the 1974 Republican primary in August by the man he succeeded six years earlier,
George Hansen (no relation). (George Hansen had vacated the seat in 1968 to run for the U.S. Senate, but lost to incumbent
Frank Church.) U.S. Senator
