PORTLAND, Ore. – Two Portland residents submitted a petition for a 2018 ballot initiative to have Oregon secede from the union and form its own country with any other states that want to join.

The Oregonian/OregonLive reports that lawyer Jennifer Rollins and writer Christian Trejbal filed the Oregon Secession Act on Thursday morning.

Trejbal told the newspaper the idea had been developing over time, but was obviously spurred by the election of Donald Trump. They chose 2018 to give Oregonians some time to think about the decision, but said they planned to collect signatures Thursday night at Pioneer Square, where an anti-Trump protest is scheduled.

The Oregon Secession Act says lawmakers "shall seek secession alone or in conjunction with other states and Canadian provinces that seek to form a new nation, including but not limited to California, Washington, Hawaii, Nevada, Alaska and British Columbia."

Meanwhile, a group called Yes Cascadia is working to "grow Cascadian autonomy and interdependence."

Many Californians have called for their state to secede.
