After college graduation, Brewster moved to Colleyville, Texas, where, as a licensed pharmacist, he owned and operated Colleyville Drug.[5] In 1968, he also began a career as a cattleman and rancher when he started Brewster Angus Farms, as well as owning a real estate business.[1] In 1977, Brewster settled in Marietta, Oklahoma.[6]
In the 1990 elections, Brewster ran for an open seat in the U.S. House of Representatives (District 3—then Congressman Wes Watkins had decided to retire from Congress and run for Governor of Oklahoma). Brewster won the heavily contested Democratic nomination against Lieutenant Governor Robert S. Kerr III.[9] He won the election to Congress in November 1990[10] in this heavily Democratic district (referred to as "Little Dixie"[11]). He was re-elected in 1992 and then again in 1994, serving from January 3, 1991, to January 3, 1997.[12]
Retirement from Congress
In December 1995, Brewster announced that he would not run for reelection to Congress in 1996.[13] He was mentioned as a possible Democratic candidate for governor in 1998, but declined to run for the nomination.[14]
After he left Congress, Brewster joined R. Duffy Wall and Associates, a Washington, D.C., lobbying firm.[15] In 2001, he served as president and chief operating officer of this firm. He was also chief executive officer and chairman of the Capitol Hill Consulting Group.[16]
Personal life
Brewster married Mary Sue "Suzie" Nelson in 1963, and the couple had three children: Balynda Karel, Betsy Kecia, and Bradley Kent. On January 31, 1990, Betsy Kecia and Bradley Kent died in a plane crash with friends of the family.[17]
Brewster died on October 3, 2022, at the age of 80. He died at his home in Marietta following a battle with cancer.[4]
