NEW YORK Two progressive activists were hospitalized overnight Sunday after they were beaten at an event featuring conservative provocateur James OKeefe.

Neither fought back or otherwise engaged in violence, according to Peter James Callahan, a third activist at the event who captured some of it on video, screenshots of which are below.

Ryan Clayton, one of those injured, said he was choked, kicked in the head and thrown down a flight of wooden stairs. Clayton runs the group Americans Take Action , which recently took part in a counter-sting against OKeefes Project Veritas. A separate Veritas operation, undertaken around the same time, resulted in the arrest of an activist for allegedly plotting to stink-bomb the DeploraBall, an inaugural ball.

The other injured activist, Jason Charter, said he was beaten and kicked, and his phone and camera were stolen. Both men were released from the hospital Monday.
