The Catholic school in Kentucky whose students faced off with a Native American elder in a video that went viral was closed Tuesday amid security concerns — while protesters gathered outside the diocese in Covington, according to reports.

“After meeting with local authorities, we have made the decision to cancel school and be closed on Tuesday, January 22, in order to ensure the safety of our students, faculty and staff,” principal Robert Rowe said in a statement posted on Cincinnati’s WKRC-TV.

“All activities on campus will be canceled for the entire day and evening. Students, parents, faculty and staff are not to be on campus for any reason,” he added.

“Please continue to keep the Covington Catholic Community in your prayers.”

Other schools were also closed due to inclement weather, and Covington Catholic High appeared on WKRC’s school closure list — but the weather was not mentioned in Rowe’s statement.

The announcement was made on the first day of school since the incident between students from the Park Hills school wearing MAGA caps and Omaha National tribal elder Nathan Phillips on the steps of the Lincoln Memorial in Washington, DC.

The students were in the capital for the annual March for Life anti-abortion rally.

On Monday, Kenton County Commonwealth’s Attorney Rob Sanders said officials at the school met with local law enforcement to come up with a plan to ensure student safety.

Sanders told CNN the move came after threats against the school and some students.

“I think anybody threatening schoolchildren is completely wrong, and I won’t stand for it personally,” said Lance Soto, co-chairman of the American Indian Movement Chapters of Indiana and Kentucky, which planned a protest for Tuesday morning, Newsweek reported.

“Those people are not affiliated with us,” he added.

The AIM chapters of Indiana, Kentucky and Ohio planned the protest at the Diocese of Covington as a “peaceful vigil to confront racism,” according to the Washington Times.

They originally planned to be outside of Covington Catholic High but the group said it understands the concerns about showing up outside the school itself.

“Our concern is the adults — we want to hold the administration, teachers and seemingly absent chaperones accountable in this situation,” AIM said in a Facebook post.

Thomas Pearce, co-chairman of AIM’s Indiana and Kentucky chapters, said they are calling for the Diocese of Covington to discuss changes in curriculum.

“We’re going to call for the Archdiocese in Covington to adopt policies of curriculum changes that will educate the students about the history of … between Catholics and American Indians,” he said, according to Fox 19.

AIM also addressed the viral video of the incident involving CovCath students and the 64-year-old tribal leader.

“We have seen the entire hour and forty-six minute video and stand by Nathan Phillips. While this longer video gives better context to the situation, it still does not absolve those boys of their behavior,” AIM said.

“Nathan Phillips is a respected elder. He stepped in to what he saw was a tense situation between the Black Hebrew Israelites, who were yelling harmful things at Natives and the school group, and the school group who were becoming increasingly worked up.”
