Cooley was elected to the
Oregon State Senate in 1992. In 1994, midway through his State Senate term, Cooley was elected to the
United States House of Representatives as a Republican from the 2nd district. In the
104th Congress, Cooley was an advocate of private property rights, American military superiority,
tort reform to limit recovery by plaintiffs, and other planks of the Republican Party's proclaimed
Contract with America. In April 1996, the
Medford, Oregon Mail Tribune questioned Cooley's statement in the 1994 Voter's Guide that he had served in the
Army Special Forces in Korea. A special nominating convention chose former six-term incumbent Republican
Bob Smith, who had retired two years earlier, to replace Cooley on the ballot. Smith went on to defeat Democrat Mike Dugan in the November election.{{cite news In December, Cooley was indicted for lying about his military service in the 1994 voter's pamphlet.{{cite news ==Tax evasion conviction==
