Richard Spencer, a white-nationalist and leader of the alt-right movement, was punched in the face by a protester in Washington D.C. following Trump's inauguration.

Spencer was posing for a photograph at the corner of 14th and K Street around 2:30 p.m. when a masked person approached and punched Spencer twice in the face.

"Someone ran up behind him and clocked him in the face. Somebody in a mask. Spencer kept talking," a witness told Jezebel. "Then it happened again."

"You hate black black people!" another protester on the scene yelled, reports McClatchy DC.

"I don't hate black people," Spencer replied, as another protestor ran up and spat in Spencer's face, the publication said.

The witness told Jezebel that Spencer is likely going to have "a big face tomorrow."

Spencer was then ushered into a cab by his assistant.

Protests sprouted up around Washington throughout the day — resulting in more than 90 arrests — though most of the protesters were peaceful.

Spencer himself confirmed the incident in a tweet on Friday afternoon, saying he was "physically assaulted twice by antifas" (short for anti-fascist protesters).

Spencer emerged as a prominent Trump supporter during the chaotic 2016 presidential election — most notably leading a group of supporters in a Nazi-esque salute at a November conference in Washington D.C. The president disavowed the group that same month.

Spencer released a video on the live-streaming app Periscope on Friday afternoon where he discussed his version of the events that took place.

"Someone came out of nowhere, and punched me. He didn't really land one, and it didn't hurt that much. But it was pretty remarkable," Spencer said.

Spencer described how, as he was being interviewed by journalists following the incident, the same person came back and "sucker-punched" him in the ear. Spencer said that after the attack, witnesses circled around him to protect him from further blows.

But that wasn't the end of Spencer's troubles. Spencer said that as he moved away from the protesters, another person came up and spat on him.

"This was three physical assaults, really serious physical assaults, that occurred," Spencer said.

"I'm afraid this is going to become the meme to end all memes."
