SPOKANE, Wash. (AP) — Republican U.S. Rep. Dan Newhouse of Washington state voted to impeach President Donald Trump this year, and he has the primary challengers to prove it. At least three Republicans have said they will challenge Newhouse in next year’s election for the 4th District U.S. House seat, representing central Washington. They include former gubernatorial candidate Loren Culp, state Rep. Brad Klippert, R-Kennewick, and Prosser businessman Jerrod Sessler. Newhouse was easily re-elected last November, and has been in Congress since 2015. He has said he will run for a fifth term in 2022, even though many Republican county organizations demanded that Newhouse resign after becoming one of just 10 House Republicans who voted to impeach Trump this year.
