A group of protesters interrupted Senate proceedings Tuesday night by loudly singing and chanting Native American songs in the chamber, reportedly to celebrate the failure of a bill to approve the Keystone XL pipeline. 

The demonstrators began their show shortly after the Senate rejected the bill.

The group of five was singing what sounded like a Native American song. Two of the protesters wore clothing with Native American affects.

U.S. Capitol Police dragged the group out into the hallway on the third floor of the Capitol and stood them against a wall while they were handcuffed. They were then paraded down a corridor and one of the protesters, who appeared to be the ringleader, began singing again.

Mediaite reported that the group, apparently from the Lakota tribe in South Dakota, was celebrating the Senate’s rejection of the pipeline.

The group was arrested for “disrupting Congress.”
