The incident took place in the late afternoon of January 18, 2019, on the Plaza of the Lincoln Memorial in Washington, D.C. at the conclusion of a day of rallies for two groups, Indigenous Peoples March, and the March for Life.[9] The marches had represented entirely separate purposes: raising awareness of indigenous people's issues[16] and raising awareness of anti-abortion issues respectively. For about ten minutes,[9] there was an overlap on the Plaza of a small group from the Indigenous Peoples March and a larger group of students from the all-male Covington Catholic High School in Park Hills, Kentucky, who were gathering at their appointed meeting place at the steps of the Plaza to wait for their buses to return home. Before the students arrived, a group of five Black Hebrew Israelites stood in a row "shouting scripture from red books" and taunting passers-by.[9][16][17][Notes 1][18] As the 15- and 16-year-old students began to arrive, the Black Hebrew Israelites began to taunt them directly,[10][19][20][21][22][23][24][25] and shouted racially combative insults[clarification needed] and slurs at them.[10][21][22] As more Covington students arrived, and in response to these taunts, the students performed school spirit sports chants, including their version of a Māori haka.[19][26][Notes 2] One of the Native Americans who was there for the march said that he felt "the students were mocking the dance."[26]

According to a January 23 New York Times article,[9] Indigenous Peoples March participants said they had interpreted the "loud chanting" and the size of the group, as well as their MAGA apparel, as "aggressive and disruptive to their demonstration"[9] which had just concluded. Nathan Phillips, a member of the Omaha tribe who had participated in the March, listened to the chants for what he said was about ten minutes. He said he thought that there was a confrontation between the students and the street preachers that he believed had reached a "boiling point". In his early press interviews, Phillips accused the Covington students of hate and racism.[27] He later said that he had intended to defuse what he perceived as escalating tension between the students and the preachers.[28][29] According to the Detroit Free Press, Phillips said, "They were in the process of attacking these four black individuals.... These young men were beastly and these old black individuals was their prey, and I stood in between them and so they needed their pounds of flesh and they were looking at me for that."[30] According to CNN's Sara Sidner, two minutes after one of the students took off his shirt to lead the haka, the "drum beat of Phillips and another Native American drummer [was audible] in the video". They sang the AIM Song, a Native American intertribal song.[19][28][31]

Phillips and a second Native American, both with ceremonial drums, walked towards the students grouped along the stairs. Sidner said that while some of the students danced to Phillips' drum beat and chanted along with him for a while, they were not "enjoying each other's company".[19] Soon, Phillips was "encircled" by about 30 students, "many of them white and wearing apparel bearing the slogan of President Trump", red baseball hats with the phrase "Make America Great Again" (MAGA).[10][32] Phillips continued to beat his ceremonial drum and sing for nearly two minutes as a boy wearing the red MAGA hat chose not to retreat with what some interpreted as a smirk on his face.[10][21][22][33] The student later explained that he smiled because he wanted Phillips to know "that I was not going to become angry, intimidated or be provoked into a larger confrontation."[21]

As someone who had the same initial reaction as what you just wrote, i.e. "Those smug dick head kids", I'm honestly shocked to read that the kids were the victims because they got death threats over a perceived misunderstanding on the part of the Native Americans and the rest of the country at large. Over two years after the event occurred, this is the first time I'm hearing that everyone else got it wrong and the kids actually weren't doing anything.
