Protesters clashed with a white nationalist group in Washington, D.C. on Saturday, leaving one of the members of the group with a bloody gash on his head.
The National Policy Institute, a think tank that describes itself as "dedicated to the heritage, identity, and future of people of European descent in the United States," held a conference to celebrate Donald Trump's election.
The conference was held at the Ronald Reagan Building, about a block from the new Trump International Hotel.
WATCH | Here's how the fight looked.
Hundreds of protesters showed up to the conference. The protests were peaceful until two people from NPI showed up with a video camera and microphone, CNN reports. A woman from NPI asked a protester if he was a "self-hating white person." Then another protester hit the video camera, and a fight broke out as protesters yelled "Die, Nazi, die!"
The man from NPI came out of the fray with a bloody cut on his forehead. Two protesters were handcuffed by police. The rest continued to protest peacefully.
A group called Smash Racism DC called for action the day before the conference.
I love the smell of Napalm in the morning. And we just napalmed the [expletive] out of Hillary Clinton and everyone who supports her.
More on the Institute
NPI is led by Richard Spencer, who coined the term "alt-right." His Twitter account, along with the Institute's and several other alt-right accounts, were banned in a recent crackdown on hate speech.
