A group of high school students from Kentucky sparked online outrage when they harassed and mocked participants in the Indigenous People's March in Washington, D.C. on Jan. 18. In a series of viral videos, the students from Paris Hills, Kentucky's Covington Catholic High School can be seen chanting and tomahawk-chopping the air around men playing hand drums and singing. 

Many of the students were wearing Donald Trump's "Make America Great Again" merchandise, including one teenager who stepped in front of the drummer and stood inches away from him throughout the song. The school was in D.C. to take part in a pro-life protest on the National Mall when they crossed paths with the march.

Covington Catholic High School said they were investigating the incident and will take "appropriate action."

"This behavior is opposed to the Church’s teachings on the dignity and respect of the human person," Covington the school and the Diocese of Covington said in a joint statement. "The matter is being investigated and we will take appropriate action, up to and including expulsion."

The incident comes days after Donald Trump used the term "Pocahontas" and the Wounded Knee massacre to mock Senator Elizabeth Warren on Twitter.
