WASHINGTON SQUARE, MANHATTAN — A group of anti-fascism activists tried to physically block Canadian right-wing comedian and Vice Media co-founder Gavin McInnes from entering the NYU Kimmel Center for University Life on Thursday evening, where he was invited to give a speech by the NYU College Republicans.

Eleven people were arrested Thursday night, police said, after a scuffle broke out between cops and activists on both the right and left. Photos and videos from the scene showed NYPD officers tackling protesters who had apparently rushed McInnes.

A "Make America Great Again" hat was also set on fire at the protest, and cops had to stomp on it to put out the flames, according to DNAinfo reporter Noah Hurowitz: Police have extinguished a flaming MAGA hat outside NYU's Kimmel Center pic.twitter.com/FglvK1X13r

That protest reportedly turned violent. An NYU campus group called "NYU Anti-Fascists" planned their protest for 6:30 p.m. Thursday at 60 Washington Square South. McInnes arrived to speak around 7 p.m.
