On 27 August 2021, at least four protesters demonstrating against the Enbridge Energy Line 3 oil pipeline were arrested at the Minnesota State Capitol. The arrests happened around noontime after dozens of Minnesota State Patrol troopers surrounded a teepee on the capitol mall where demonstrators were holding a ceremony, playing drums and singing traditional Native American songs. A group called the "Water Protectors" say they were in a religious ceremony, protected by treaty rights. Those who refused to leave were arrested.
