Since Hawaii became a U.S. state in 1959, it has sent congressional delegations to the United States Senate and United States House of Representatives. Each state elects two senators to serve for six years. Members of the House of Representatives are elected to two-year terms, one from each of Hawaii's congressional districts.
These are tables of congressional delegations from the state of Washington to the United States Senate and United States House of Representatives.. The current dean of the Washington delegation is Senator Patty Murray, having served in the Senate since 1993.
