Donald Trump supporters Enrique Tarrio, founder of the far-right extremist group Proud Boys, and conservative activist Bevelyn Beatty say they were stabbed near the White House

Members of the far-right extremist group Proud Boys and a Trump supporter were stabbed during a brawl after watching US election coverage at a bar.

Video posted on social media shows a group of people brawling on a pavement just blocks from the White House. As the fight ends, conservative activist Bevelyn Beatty says “they stabbed me” as she clutches her lower back.

Enrique Tarrio, founder of the Trump-supporting Proud Boys, claims he was slashed in the stomach.

Beatty claims they were knifed by Black Lives Matter (BLM) “kids”, but the local BLM chapter said none of its activists were involved and the claims were “a lie”.

Police not have yet publicly confirmed how the incident started or commented on claims that the other people were part of the Black Lives Matter movement.
