The failure of a bill supporting the Keystone XL pipeline in the Senate brought about a celebratory song from Native American demonstrators in the chamber, according to video posted online on Tuesday.


The footage shows Sen. Elizabeth Warren (D-MA) presiding over the Senate and moving to move to executive session when she is interrupted by one protester, identified by the Washington Post as Greg Graycloud of the Lakota Tribe in South Dakota.

The bill garnered 59 votes in support, one short of the number needed to pass. Fourteen Democrats joined 45 Republicans in voting for the pipeline.

Warren quickly called for the sergeant-at-arms to "restore order." An independent journalist, Radical Media, reported that five protesters were arrested in all and taken from the Senate chamber.

After Graycloud's song, other protesters chanted, "Senator Landrieu, whatcha gonna do?," a reference to Sen. Mary Landrieu's (D-LA) attempt to gather the 60 votes needed for the bill to pass. Landrieu is currently headed for a runoff election next month against Republican Bill Cassidy.

Another activist group, DC Action Lab, posted a picture online from outside Sen. Michael Bennet's (D-CO) office, saying they were threatened with arrest if they did not stop singing.

While lawmakers have debated on whether to move forward on the Keystone pipeline, both environmental activists and Native American tribes have spoken out against it. On Monday, the president of the Rosebud Sioux Tribe, Cyril Scott, said in a statement that his group was "outraged" by a House vote last week approving the project.

"We are a sovereign nation and we are not being treated as such," Scott said. "We will close our reservation borders to Keystone XL. Authorizing Keystone XL is an act of war against our people."
