Romano Louis "Ron" Mazzoli (November 2, 1932 – November 1, 2022) was an American politician and lawyer from Kentucky. He represented Louisville, Kentucky, and its suburbs in the United States House of Representatives from 1971 through 1995 as a Democrat. He was the primary architect, with Senator Alan Simpson, of major immigration reform legislation. Early life and career Mazzoli, whose father immigrated to the United States from northern Italy, was born in Louisville and was a 1950 graduate of St. Xavier High School, a Xaverian Brothers boys preparatory school. He won the 1950 Kentucky boys high school doubles tennis championship with fellow St. Xavier 1951 alumni George D. Koper. He graduated magna cum laude from the University of Notre Dame in Notre Dame, Indiana, in 1954 and from the University of Louisville law school, first in his class, in 1960. Mazzoli served in the Kentucky Senate from 1968 through 1970. In 1969, he ran for mayor of Louisville, and came third in the Democratic primary. U.S. House of Representatives Mazzoli was elected to the U.S. House of Representatives in 1970, defeating Republican incumbent William Cowger by 211 votes, the closest House election of that year. Serving for the next 24 years, he was Chairman of the House of Representatives' Immigration, International Law and Refugees Subcommittee for twelve years. He also served on the Small Business, Intelligence and District of Columbia Committees. In 1981, Mazzoli, an anti-abortion Democrat, introduced, along with Republican Henry Hyde, the Human Life Amendment, a proposed constitutional amendment which would ban all abortions by granting legal protection to all unborn children in the United States. Ultimately, the amendment failed to amass the 218 votes necessary to pass. Mazzoli authored the Simpson-Mazzoli Immigration Reform and Control Act, later known as the Immigration Reform and Control Act of 1986, and cosponsored it with Republican Senator Alan K. Simpson. The bill enacted the first U.S. laws to sanction employers who hired undocumented aliens; it also granted an amnesty for aliens already living and working in the United States. After five years of debate and compromise, the Simpson-Mazzoli Bill was ultimately signed into law in November 1986. Also in 1986, Mazzoli was one of the House impeachment managers who prosecuted the case in the impeachment trial of Judge Harry E. Claiborne. Claiborne was found guilty by the United States Senate and removed from his federal judgeship. Mazzoli did not run for
