He received his bachelor's degree from the University of Notre Dame and his LL.B. from Marquette University Law School. He practiced law in Milwaukee for several years before running for office. He was a delegate to the 1960 Democratic National Convention, supporting the presidential nomination of then-Senator John F. Kennedy. Brennan was elected to the Wisconsin State Senate in 1958, representing part of the city of Milwaukee. He served two years but resigned in April 1961 in anticipation of his confirmation as United States Attorney. In March 1961, newly elected president John F. Kennedy nominated Brennan to serve as United States Attorney for the Eastern District of Wisconsin. His nomination was reported favorably out of the Senate Judiciary Committee on May 4, 1961, and he was confirmed on May 8. Brennan ultimately served through the Kennedy administration, and continued to serve through the presidency of Lyndon B. Johnson. He remained in office until his successor was appointed by President Nixon in 1969. In 1972, Brennan was elected City Attorney for Milwaukee, serving three four-year terms. He was defeated in the 1984 election by his subordinate, Grant Langley, despite strong backing from the then-Mayor Henry Maier. After his defeat, he worked briefly as a staff attorney for the Milwaukee Metropolitan Sewerage District before resigning from that role in 1988. Brennan died on June 6, 2021.
