Cop Screams for Help While Getting Crushed by Capitol Rioters

Here's an up-close and graphic view of the kind of violence police were facing as the mob stormed the Capitol -- an injured officer screaming for help as the rioters crushed him between a riot shield and a door.

The intense video captures the moment insurrectionists tried to bully their way inside the halls of Congress, clashing with the Capitol Police Department and leaving one officer on the front lines fighting for his life.

The cop was bleeding from his mouth as he was pinned against a door guarding the entrance to the west side of the Capitol. You could hear the mob yelling "heave ho" as they attempted to push through the police line -- and officers were swinging batons and deploying pepper spray to keep them back.
