Wiley Mayne

In 1966, Mayne ran for Congress in the now-obsolete Sixth Congressional District in Northwest Iowa and defeated Democratic freshman incumbent Stanley L. Greigg.^[4] Mayne was elected four times to the House, where he served on the House Agriculture Committee and the House Judiciary Committee. While serving on the House Agriculture Committee, a major issue of the era was a sudden and swift decline in the United States cattle market.^[3] In 1973, he was made a delegate to the Food and Agriculture Organization in Rome.^[2] One of Mayne's Congressional aides was future actor and congressman Fred Grandy.^[5]

As a member of the House Judiciary Committee, Mayne played an influential role in amendments to the Federal Rules of Evidence, especially those involving the admissibility of opinion testimony. His political downfall, however, came in his fourth term during his service on that Committee, when Mayne was one of ten Republican Committee members to vote against articles of impeachment against President Richard Nixon arising from the Watergate scandal. At the time of his Committee votes, Mayne believed that the proof was not sufficient to necessitate a call for impeachment. In Nixon's final days in office, however, Mayne's opinion quickly changed after evidence implicating Nixon in a subsequent coverup was made public, and he vowed to vote in favor of impeachment when the articles came before the full House.^[4] The damage, however, had been done, and Mayne lost the 1974 election to his 1972 opponent, Democrat Berkley Bedell 54.6% to 45.4%.^[6]

After leaving Congress, Mayne returned to Sioux City, Iowa, to resume his law practice.^[3] His wife, Betty, died in 2001, and Mayne continued to practice law until 2005.^[3] Mayne died in May 2007 after suffering a cardiopulmonary incident.^[4]
