SALEM, Ore. (AP) — A new recall effort emerged against one of the Republican lawmakers who left the Capitol to protest environmental legislation.

Oregon Public Broadcasting reports that Sen. Chuck Thomsen of Hood River could face an election to remove him from office if organizers can gather enough signatures.

A Hood River resident launched a recall petition against Thomsen because of his role in the walkout.

In order to force a recall election, the petition effort must gather 9,025 valid signatures by June 2, according to the Secretary of State’s Office.

Thomsen’s district stretches from the suburbs of Portland east to Hood River. The district contains around 7,000 more registered Democrats than Republicans, but non-affiliated voters make up the largest bloc.
