Tenure in Congress Bonker was elected as a moderate Democrat to the
94th and to the six succeeding Congresses (January 3, 1975 – January 3, 1989). He did not run for reelection in 1988 so he could run for nomination to the
United States Senate, where he narrowly lost in the primary to Democratic U.S. House of Representatives member
Mike Lowry, who was defeated in the general election by former Republican U.S. Senate member
Slade Gorton. During his time in the House, Bonker was a senior member of the
United States House Committee on Foreign Affairs and chairman of the Subcommittee on International Economic Policy and Trade. He also served on the President's Export Council and headed former
Speaker of the United States House of Representatives Tip O'Neill's Trade Task Force, which led to passage of the
Omnibus Trade and Competitiveness Act. During his tenure in Congress, Bonker authored and was a principal sponsor of significant trade legislation, such as the Export Trading Company Act and the Export Administration Act. Bonker helped establish the
Grays Harbor National Wildlife Refuge and the
Mount St. Helens National Volcanic Monument, added
Protection Island to the
National Wildlife Refuge system, preserved the Point of Arches in the
Olympic National Park, added 250,000 acres (1000 km2) to the 1984 Washington Wilderness Act, and banned the export of
western redcedar. == Later career ==
