PORTLAND, Ore – They’re more than a thousand miles apart, but people in Portland are showing support for pipeline protesters in North Dakota.

Monday afternoon, several set up tents in front of the Army Corps of Engineers office in Northeast Portland, and they camped overnight into Tuesday morning.

The camp-in was led by the 7th Generation Environmental Alliance, in response to the Army Corps of Engineers request to close the camp of protesters in North Dakota by Monday.

That camp and protest on federal land is led by the Standing Rock Sioux tribe. Leaders say the Dakota Access Pipeline will put the tribes’ water supply and cultural sites at risk. Thousands have protested for months.

Protesters in Portland started camping out Monday night when Army Corps employees left for the day, and they were still there in the morning when the employees arrived at work, to show support for the Standing Rock Sioux tribe.

“It’s symbolic there’s 20-mile-an-hour winds, snows. They are camped out in the cold out there right now and we wanted to camp out in solidarity with them,” said Phillip Killary, with 7th Generation Environmental Alliance.

The group plans to pack up the tents Tuesday and move on. Several other events are planned this week and next week, including a big rally on Monday in Portland, the day of the Army Corps of Engineers deadline for the protesters in North Dakota.
