Mr Spencer was punched by a masked protestor amid President Trump's inauguration.
Richard Spencer, who garnered notoriety in November for his “Hail Trump” speech, was socked twice in the face by masked protestors on Friday.
Mr Spencer was speaking in a filmed interview about the reaction to Mr Trump’s swearing-in when he was attacked.
As he gives his take on America’s political climate, a protester interrupts him and asks: “Do you like black people?”
Mr Spencer turns and replies: “Yeah, sure.”
Another demonstrator off-screen asks him why “neo-Nazis love you, if you’re not a neo-Nazi” – a claim which Mr Spencer denies.
Mr Spencer was giving an interview on film before the attack happened.
A woman interrupts the interview to ask Mr Spencer: "Do you like black people?"
He said: “Neo-Nazis don’t love me, they kind of hate me, actually.”
The altercation continues as the interviewer attempts to ask another question about a badge on Mr Spencer’s jacket of Pepe the Frog – a symbol seen by many to be associated with white nationalism and President Trump.
But as Mr Spencer begins to explain the badge, a masked protester comes in from the left of the screen and punches him in the face.
