Greg Walden, Oregon's only Republican member of Congress, will not seek re-election in 2020.

Walden, 62, told Politico he was sure he'd win another run for office in his sweeping congressional district—which spans the entire Eastern border of Oregon and stretches to the western edge of the Cascades.

"But I also know that for me, the time has come to pursue new challenges and opportunities," he told Politico. “So, I will not seek re-election to the U.S. House of Representatives, nor election to any other office, but instead I will close the public service chapter of my life, thankful for the friends I’ve made and the successful work we’ve done together."

Walden serves as the top Republican on the House Energy and Commerce Committee, and has introduced legislation that expands transparency within the FCC and satellite broadcast programs. Walden has been considered a moderate Republican in DC, where he has opposed Donald Trump's border wall crusade and has called on Congress to address climate change. But don't be fooled: Walden's also refused to join his fellow Oregon members of Congress in opposing a policy that would allow the feds to deny immigrants permanent residency if they’re poor, ignored an investigation into a possible anti-LGBTQ hate crime, stonewalled affordable housing providers in his district, and has happily accepted tens of thousands of dollars from the National Rifle Association.

Walden's also stood behind Trump through the recent investigation into Trump's possibly impeachable Ukrainian demands.

What's more, he's backed homegrown terrorism. In July 2018, Walden called on the White House to pardon Dwight and Steven Hammond, the Oregon ranchers who committed arsons and threatened federal refuge workers during the Malheur Wildlife Refuge standoff. Less than a month later, Trump pardoned both men and commuted their sentences.

Walden joins a growing list of House Republicans announcing their retirement this election cycle, giving way for an undoubtedly interesting—if not hopeful—2020 race.
