Who is my U.S. representative in WA-04?
If you're referring to Washington's 4th Congressional District (WA-04), your current U.S. Representative is: Dan Newhouse (Republican) Ziplook WA-04 covers much of central Washington, including areas such as Yakima, the Tri-Cities (Kennewick, Pasco, Richland), Moses Lake, Sunnyside, and surrounding communities. If you meant a specific address within Washington and want to verify that it's in WA-04 (district boundaries can be confusing), tell me your ZIP code or city and I can confirm your representative.
