Former UFC champion Ronda Rousey delivered food and supplies to the Standing Rock protesters in North Dakota.

An image posted to Twitter shows Rousey and fellow Olympic judo athlete Paulina Macias standing in solidarity with those battling the planned building of the $3.8 billion Dakota Access oil pipeline.

The Sioux tribe of Standing Rock has been at the forefront of the ongoing protest. They are concerned that their drinking water will be contaminated if the pipeline is built.

In an interview with TMZ Sports, activist leader Linda Black Elk said Rousey is an "incredible person" and her support means the world to the protesters.

“That’s what keeps us going, that kind of support and just the morale booster it was," Black Elk said. "That’s what keeps us going. It means everything to us.”
