Administrators at an elite Catholic high school in Kentucky have closed the campus Tuesday due to “security concerns” after its students were shown on video in a confrontation with a Native American activist. A Cincinnati Fox TV affiliate reports Covington Catholic Principal Robert Rowe issued an email to students’ families and local media canceling school and warning everyone to stay off campus. “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,” Rowe’s email reads. “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. Please continue to keep the Covington Catholic Community in your prayers.” Footage of the Friday incident at the Lincoln Memorial in Washington, D.C. ignited a firestorm, with all parties subsequently claiming innocence and facing threats.
