80th Oregon Legislative Assembly

The 80th Oregon Legislative Assembly convened for its first of two regular sessions on January 22, 2019, and met for three special sessions, the last of which concluded on December 21, 2020.

In the November 2018 elections, the Democratic Party of Oregon gained supermajority status in both houses: one seat in the Senate for an 18–12 majority, and three seats in the House for a 38–22 majority. From May 29 to June 28, 2019, the 10th senate district was vacant, following the death of senate minority leader Jackie Winters.

Senate
The Oregon State Senate is composed of 18 Democrats and 12 Republicans. Democrats gained one seat in District 3.

Senate President: Peter Courtney (D–11 Salem) President Pro Tempore: Laurie Monnes Anderson (D–25 Gresham) Majority Leader: Ginny Burdick (D–18 Portland) until May 22, 2020; Rob Wagner (D-19 Lake Oswego) after Minority Leader: Herman Baertschiger Jr. (R-2 Grants Pass)

Events
In May 2019, Republican state senators refused to attend senate sessions for four days, opposing a $2 billion tax package for K-12 schools. They only returned after making a deal with Oregon Governor Kate Brown that Democratic state senators would not field bills on guns and vaccines, would "reset" a cap-and-trade bill, and promised not to walk out again. Previous Oregon legislative walkouts have occurred in 2007 for Republicans and 2001, 1995 and 1971 for Democrats.

From June 20, 2019, all 11 Republican state senators for Oregon, including Girod, refused to show up for work at the Oregon State Capitol, instead going into hiding, some even fleeing the state. Their aim was to prevent a vote on a cap-and-trade proposal, House Bill 2020 that would dramatically lower greenhouse gas emissions by 2050 to combat climate change. The Senate holds 30 seats, but 1 is vacant due to the death of Republican Jackie Winters. Without the Republican senators, the remaining 18 Democratic state senators could not reach a quorum of 20 to hold a vote before the end of the legislative session on June 30, 2019. This tactic is known as quorum-busting.

Oregon Governor Kate Brown sent the Oregon State Police to bring the absent Republican senators back to the Capitol. In response, Republican Oregon Senator Brian Boquist said: "Send bachelors and come heavily armed. I'm not going to be a political prisoner in the state of Oregon." Right-wing militia groups have offered support for the Republican senators, with 3 Percenters declaring they would be "doing whatever it takes to keep these senators safe", and the Oath Keepers stating: "Gov. Brown, you want a civil war, because this is how you get a civil war". On June 22, 2019, a session of the Oregon Senate was cancelled when the Oregon State Capitol was closed due to a warning from the state police of a "possible militia threat". All but 2 of the Republican senators returned to the session by June 29.

In August 2019 Governor Brown considered calling a special session to address the impacts of recent death penalty legislation, but declined to do so when it became clear that the House of Representatives lacked the votes to ensure passage.

In February 2020 Republican senators walked out again, still in protest of the cap and trade legislation.
