A video taken during the riots at the US Capitol building on Wednesday shows a police officer shouting in pain as he is crushed in a doorway by a mob of Trump supporters.

The rioters were trying to force their way through an entrance on the west side of the building, according to CNN, which aired the footage Friday night.

The video shows a group of officers in riot gear attempting to block the doorway, while a large mob collectively tries to push through in unison.

At some point, an officer gets pinned in the doorway, and exclaims "help!" in between shouts of pain.

The person who took the video told CNN police succeeded in keeping people from moving further into the building at this location.

Rioters did breach the building, causing lawmakers to evacuate and leaving five people dead, including one police officer.

Capitol Police confirmed Officer Brian D. Sicknick passed away after sustaining injuries while "physically engaging with protesters."

The riots occurred as Congress was meeting for a joint session to certify President-elect Joe Biden's victory.

During a rally protesting the outcome of the election, President Donald Trump spoke and incited his supporters to march to the Capitol and "stop the steal," a reference to his unsubstantiated claims of a fraudulent election.
