Video shows US Capitol police officer crushed by door during riot by MAGA mob

The officer screamed for help as he was crushed

Video from the US Capitol insurrection captured the moment a Capitol police officer was crushed between a riot shield and a metal door as rioters pushed into the building.

The footage shows a young Capitol police officer bleeding from the mouth and screaming for help as the crowds crush him between the objects.

Masses of police officers clash with rioters in the video. They spray pepper spray and attempt to beat back the Trump supporters with batons as they throw punches and try to push their way through the police line.

The footage shows just one scene from the chaos that erupted at the Capitol on Wednesday after Donald Trump told his supporters to march on the Capitol in an attempt to overturn the results of the 2020 election.

Five people died in the attack on the Capitol. Four Trump supporters died, including Ashli Babbit, a QAnon adherent who was shot in the neck and died while trying to breach the doors.

Another Trump supporter died after accidentally tasing himself. He suffered a heart attack and died.

Two other Trump supporters, a man and a woman, also died due to "medical emergencies" they suffered during the riot.

The fifth death was a Capitol police officer, Brian Sicknick, who The Chicago Sun reported was beaten with a fire extinguisher. Mr Sicknick apparently made it back to his division office and collapsed from his injuries. He later died of his injuries.

Lawmakers including House Speaker Nancy Pelosi and Rep. Tim Ryan are calling for investigations into the security breach at the Capitol.

Capitol Police Chief Steven Sund resigned on Thursday after calls from Ms Pelosi for him to step down from his position.

Ms Pelosi also said the House Sargent-at-Arms would resign, and Senate Democratic leader Chuck Schumer said he would fire the Senate Sargent-at-Arms if he did not resign by the time Democrats take power in the Senate later this month.

Sen. Ben Sasse, a Republican, lamented the deaths.

"None of this should have happened," he said. "Lord, have mercy."
