WASHINGTON — Longtime Democratic Rep. Jim McDermott of Washington state is announcing his retirement.

That's according to a Democratic official who tells The Associated Press that McDermott has been making calls to colleagues to let them know.

The official spoke on condition of anonymity ahead of a Monday news conference McDermott scheduled in Seattle.

McDermott, 79, is in his 14th term representing Seattle. He's known as an outspoken liberal in Congress, focusing on inequality issues and attacking Republican policies. He once drew attention for leaving out the words "under God" when leading the Pledge of Allegiance in the House. He later said it was an inadvertent omission.

McDermott becomes at least the 30th House member to announce plans to retire or seek other office.
