SALEM, Ore. (AP) — A walkout by most Republicans in the Oregon Senate is delaying action on gun safety, abortion rights and gender-affirming health care bills extended to a fifth day Sunday.

Senate President Rob Wagner adjourned the body until Monday morning because a quorum could not be reached.

“The sergeant-in-arms has reported that unexcused members cannot be located, therefore, there is no quorum for the Senate to conduct business,” Wagner said after a 9-minute session.

On Thursday, Democratic Majority Leader Kate Lieber told the AP the walkout “is about abortion, guns, right? And transgender rights. This is about walking out on bills that are important to Oregonians.”

Republican Minority Leader Tim Knopp refused to confirm the pending legislation is the only factor keeping them from coming to work.

“Our goal is to educate the public and to bring this session back into legal conformity and in this case, not passing or trying to pass unlawful and unconstitutional bills,” Knopp said.

Republicans have staged walkouts before, but this year legislators with 10 unexcused absences are disqualified for reelection, thanks to a new constitutional amendment overwhelmingly approved by voters in November.

Many of the walkout participants are now at 5 absences. Members who were out Sunday, like Sen. Cedric Hayden, said Republicans want “a balanced process where the voices of all Oregonians are heard. That’s just simply not the case at the moment when Senate Democrats believe Measure 113 gives them the luxury of not having to negotiate with the other political parties represented in the Capitol.”

Lieber isn’t having it.

“Voters spoke very loudly when they passed ballot Measure 113,” she said. “So, I fully expect that they will be back in the building, and we will continue to do the work on the floor of the Senate.”

The boycott comes as several statehouses, including in Montana and Tennessee, have become battlegrounds between conservatives and liberals. Oregon has increasingly been divided between liberal population centers like Portland and Eugene and its mostly conservative rural areas.

The Senate will hold another roll call at 10:30 a.m. Monday.
