Alt-right leader Mike Cernovich punched in the face at Tax March rally

Controversial alt-right provocateur Mike Cernovich appears to have been punched in the face at an anti-Trump rally in Austin, TX on Saturday after repeatedly yelling "Bill Clinton is a rapist" at the crowd.

The right-wing vlogger livestreamed his protest of the rally calling for President Trump to release his tax returns, and the footage appears to show rally goers shouting obscenities, pushing and shoving protest signs in front of Cernovich's face.

The livestream on Periscope then abruptly ends when Cernovich's phone falls after seemingly taking a hit.
