A crowd of teenagers surrounded a Native American elder and other activists and appeared to mock them after Friday's Indigenous Peoples March at the Lincoln Memorial.
Videos of the confrontation show a smiling young man in a red Make America Great Again hat standing directly in front of the man, who was playing a drum and chanting. Other kids could be seen laughing, jumping around and seemingly making fun of the chants.
Nathan Phillips, an elder with the Omaha tribe, said the confrontation felt like "hate unbridled." In the moment, he said he was scared for his safety and the safety of those with him.
The behavior of the students from Covington Catholic High School -- an all-boys' school in Northern Kentucky -- triggered widespread condemnation from lawmakers and celebrities as well as the school district, the mayor of the neighboring town and Covington's Roman Catholic Diocese.
CNN's Jake Tapper obtained a statement on Sunday from Nick Sandmann, a junior at Covington Catholic High School, who said he is the student in the video. Sandmann said he was trying to defuse a tense situation and denied insinuations that anyone in the crowd was acting out of racism or hatred.
"I was not intentionally making faces at the protester. I did smile at one point because I wanted him to know that I was not going to become angry, intimidated or be provoked into a larger confrontation. I am a faithful Christian and practicing Catholic, and I always try to live up to the ideals my faith teaches me -- to remain respectful of others, and to take no action that would lead to conflict or violence."
He cautioned against rushing to judgment based on the short time captured on the videos and encouraged people to watch longer clips available online, "as they show a much different story than is being portrayed by people with agendas," he said.
"I am mortified that so many people have come to believe something that did not happen -- that students from my school were chanting or acting in a racist fashion toward African-Americans or Native Americans. I did not do that, do not have hateful feelings in my heart, and did not witness any of my classmates doing that."
The person who shot the videos described the atmosphere as tense.
Kaya Taitano, a student at the University of the District of Columbia, participated in the Indigenous Peoples March earlier in the day. She said the teens were chanting things like "Build the wall" and "Trump 2020." Those chants were not audible in videos reviewed by CNN.
"I did not feel safe in that circle," she said.
Taitano said the whole incident started when the teens and four young African-Americans, who'd been preaching about the Bible nearby, started yelling and calling each other names.
Another video shot before the encounter shows men who identify as members of the Hebrew Israelites taunting the students and other passersby with racist slurs.
It got pretty intense, Taitano said, so Phillips started playing his drum and chanting what she was told was a healing prayer, to help defuse the situation.
Phillips walked through the crowd, and Taitano said things were starting to calm down until he got to the grinning boy seen in the video.
"This one kid just refused to move and he just got in Nathan's face," she said.
Other boys circled around, she said. "They just surrounded him and they were mocking him and mocking the chant. We really didn't know what was going to happen there."
Phillips is a Vietnam veteran who says he served between 1972 and 1976. He is a former director of the Native Youth Alliance and holds an annual ceremony honoring Native American veterans in Arlington National Cemetery.
"I was scared, I was worried for my young friends. I don't want to cause harm to anyone," Phillips told CNN's Sara Sidner. "I don't like the word 'hate.' I don't like even saying it, but it was hate unbridled. It was like a storm."
The crowd kept growing as Phillips and the boy stood face to face, but Phillips kept on chanting and playing his drum.
"What the young man was doing was blocking my escape. I wanted to leave. I was thinking, 'How do I get myself out of this? I want to get away from it,'" Phillips said.
But Sandmann said it was clear to him that Phillips had singled him out for a confrontation, although he was not sure why.
He said the incident began when a group identifying themselves as the Hebrew Israelites began to shout disparaging and vulgar comments at his group. He said the students began using school spirit chants -- with permission from teachers -- in response to the taunts.
He denied that anyone in the group said "build the wall" or used hateful or racist language toward Phillips.
"Our chants were loud because we wanted to drown out the hateful comments that were being shouted at us by the protesters," he said.
"The protester everyone has seen in the video began playing his drum as he waded into the crowd, which parted for him. I did not see anyone try to block his path. He locked eyes with me and approached me, coming within inches of my face. He played his drum the entire time he was in my face," Sandmann said.
"I never interacted with this protester. I did not speak to him. I did not make any hand gestures or other aggressive moves. To be honest, I was startled and confused as to why he had approached me. We had already been yelled at by another group of protesters, and when the second group approached I was worried that a situation was getting out of control where adults were attempting to provoke teenagers."
Taitano said the standoff continued until a chaperone came and led the teens away for a photograph.
The school's website said a group of students had planned to attend Friday's March for Life rally in Washington.
The school is part of the Roman Catholic Diocese of Covington, and in a statement given to CNN affiliate WLWT, spokeswoman Laura Keener said the diocese would investigate the incident and take appropriate action.
"We condemn the actions of the Covington Catholic High School students towards Nathan Phillips specifically, and Native Americans in general, Jan. 18, after the March for Life, in Washington, D.C. We extend our deepest apologies to Mr. Phillips. This behavior is opposed to the Church's teachings on the dignity and respect of the human person.
"The matter is being investigated and we will take appropriate action, up to and including expulsion. We know this incident also has tainted the entire witness of the March for Life and express our most sincere apologies to all those who attended the March and all those who support the pro-life movement."
CNN has reached out to the school and diocese for comment.
Taitano, who is from Guam, said she was raised to treat her elders with respect so it hurt to see them treat Phillips so badly.
Phillips also appeared upset in a video Taitano posted after the confrontation. He wiped away tears as he talked about the students' actions.
"I wish I could see that energy of the young mass of young men to, you know, put that energy into, you know, making this country really, really great by helping those who are hungry, you know," Phillips said.
Full statement from Nick Sandmann:
I am providing this factual account of what happened on Friday afternoon at the Lincoln Memorial to correct misinformation and outright lies being spread about my family and me.
I am the student in the video who was confronted by the Native American protestor. I arrived at the Lincoln Memorial at 4:30 p.m. I was told to be there by 5:30 p.m., when our busses were due to leave Washington for the trip back to Kentucky. We had been attending the March for Life rally, and then had split up into small groups to do sightseeing.
When we arrived, we noticed four African American protestors who were also on the steps of the Lincoln Memorial. I am not sure what they were protesting, and I did not interact with them. I did hear them direct derogatory insults at our school group.
The protestors said hateful things. They called us "racists," "bigots," "white crackers," "faggots," and "incest kids." They also taunted an African American student from my school by telling him that we would "harvest his organs." I have no idea what that insult means, but it was startling to hear.
Because we were being loudly attacked and taunted in public, a student in our group asked one of our teacher chaperones for permission to begin our school spirit chants to counter the hateful things that were being shouted at our group. The chants are commonly used at sporting events. They are all positive in nature and sound like what you would hear at any high school. Our chaperone gave us permission to use our school chants. We would not have done that without obtaining permission from the adults in charge of our group.
At no time did I hear any student chant anything other than the school spirit chants. I did not witness or hear any students chant "build that wall" or anything hateful or racist at any time. Assertions to the contrary are simply false. Our chants were loud because we wanted to drown out the hateful comments that were being shouted at us by the protestors.
After a few minutes of chanting, the Native American protestors, who I hadn't previously noticed, approached our group. The Native American protestors had drums and were accompanied by at least one person with a camera.
The protestor everyone has seen in the video began playing his drum as he waded into the crowd, which parted for him. I did not see anyone try to block his path. He locked eyes with me and approached me, coming within inches of my face. He played his drum the entire time he was in my face.
I never interacted with this protestor. I did not speak to him. I did not make any hand gestures or other aggressive moves. To be honest, I was startled and confused as to why he had approached me. We had already been yelled at by another group of protestors, and when the second group approached I was worried that a situation was getting out of control where adults were attempting to provoke teenagers.
I believed that by remaining motionless and calm, I was helping to diffuse the situation. I realized everyone had cameras and that perhaps a group of adults was trying to provoke a group of teenagers into a larger conflict. I said a silent prayer that the situation would not get out of hand.
During the period of the drumming, a member of the protestor's entourage began yelling at a fellow student that we "stole our land" and that we should "go back to Europe." I heard one of my fellow students begin to respond. I motioned to my classmate and tried to get him to stop engaging with the protestor, as I was still in the mindset that we needed to calm down tensions.
I never felt like I was blocking the Native American protestor. He did not make any attempt to go around me. It was clear to me that he had singled me out for a confrontation, although I am not sure why.
The engagement ended when one of our teachers told me the busses had arrived and it was time to go. I obeyed my teacher and simply walked to the busses. At that moment, I thought I had diffused the situation by remaining calm, and I was thankful nothing physical had occurred.
I never understood why either of the two groups of protestors were engaging with us, or exactly what they were protesting at the Lincoln Memorial. We were simply there to meet a bus, not become central players in a media spectacle. This is the first time in my life I've ever encountered any sort of public protest, let alone this kind of confrontation or demonstration.
I was not intentionally making faces at the protestor. I did smile at one point because I wanted him to know that I was not going to become angry, intimidated or be provoked into a larger confrontation. I am a faithful Christian and practicing Catholic, and I always try to live up to the ideals my faith teaches me -- to remain respectful of others, and to take no action that would lead to conflict or violence.
I harbor no ill will for this person. I respect this person's right to protest and engage in free speech activities, and I support his chanting on the steps of the Lincoln Memorial any day of the week. I believe he should re-think his tactics of invading the personal space of others, but that is his choice to make.
I am being called every name in the book, including a racist, and I will not stand for this mob-like character assassination of my family's name. My parents were not on the trip, and I strive to represent my family in a respectful way in all public settings.
I have received physical and death threats via social media, as well as hateful insults. One person threatened to harm me at school, and one person claims to live in my neighborhood. My parents are receiving death and professional threats because of the social media mob that has formed over this issue.
I love my school, my teachers and my classmates. I work hard to achieve good grades and to participate in several extracurricular activities. I am mortified that so many people have come to believe something that did not happen -- that students from my school were chanting or acting in a racist fashion toward African Americans or Native Americans. I did not do that, do not have hateful feelings in my heart, and did not witness any of my classmates doing that.
I cannot speak for everyone, only for myself. But I can tell you my experience with Covington Catholic is that students are respectful of all races and cultures. We also support everyone's right to free speech.
I am not going to comment on the words or account of Mr. Phillips, as I don't know him and would not presume to know what is in his heart or mind. Nor am I going to comment further on the other protestors, as I don't know their hearts or minds, either.
I have read that Mr. Phillips is a veteran of the United States Marines. I thank him for his service and am grateful to anyone who puts on the uniform to defend our nation. If anyone has earned the right to speak freely, it is a U.S. Marine veteran.
I can only speak for myself and what I observed and felt at the time. But I would caution everyone passing judgement based on a few seconds of video to watch the longer video clips that are on the internet, as they show a much different story than is being portrayed by people with agendas.
I provided this account of events to the Diocese of Covington so they may know exactly what happened, and I stand ready and willing to cooperate with any investigation they are conducting.
