Ernest Oppegaard-Peltier, a citizen of the Turtle Mountain Band of Chippewa Indians, addresses a Stop Line 3 rally in front of the headquarters of the U.S. Army Corps of Engineers on Washington, D.C.

The rally took place on August 23, 2021, to call on President Joe Biden to withdraw federal permits for the controversial project, which runs through Ojibwe treaty territory in northern Minnesota. The event included a march to the White House, with participants carrying a black snake that symbolizes the oil pipeline.

Oppegaard-Peltier works with Honor The Earth, a Native-led non-profit that is organizing opposition to Line 3.
