Weicker served in the U.S. Senate for three terms, from 1971 to 1989. He gained national attention for his service on the Senate Watergate Committee, where he became the first Republican senator to call for Richard Nixon's resignation. He recalled: "People in Connecticut were very much behind President Nixon, like the rest of the country. They thought he could do no wrong, and when I was in Connecticut, I would get flipped the bird all the time, whether it was on the streets or in the car, for the role that I was playing. After Watergate was over, then the needle goes all the way the other way, and I've got huge favorability ratings." Proving this, Weicker was convincingly reelected in 1976.
