Wiggins was elected as a
Republican to the
Ninetieth and to the five succeeding Congresses (January 3, 1967 – January 3, 1979). He represented much of the territory that
Richard Nixon represented in the House from 1947 to 1950. Wiggins fiercely defended Nixon during debate on the
House Judiciary Committee over
Nixon's impeachment. However, Wiggins dropped his support after the revelation of the so-called "
Smoking Gun" tape. He had actually been invited to the White House by
Chief of Staff Alexander Haig to review the transcripts before their release. However, after reading the transcript, Wiggins concluded that the tapes proved that Nixon had indeed taken part in the plan to cover up the break-in and other illegal activities. Wiggins's earlier advocacy for Nixon saw his margin of victory reduced in the congressional elections of 1974. Re-elected in 1976, he was not a candidate for reelection to the
Ninety-sixth Congress in 1978, instead returning to private practice in
Los Angeles California from 1979 to 1982, in
Washington, D.C. from 1982 to 1984, and in
San Francisco, California in 1984. ==Federal judicial service==
