At the same moment President Trump released a videotaped message to the nation, a Capitol police officer reportedly died of a stroke.

“A police officer with US Capitol Police died from a stroke, according to WUSA9’s Bruce Leshan from US Capitol Police Union Chair Gus Papathanasiou.”

A source confirmed to NewsNation D.C. Bureau reporter Alexandra Limon the officer was taken off life support and died after being struck in the head with a fire extinguisher by a rioter.

The name of the officer has not yet been released and no information was given on where the officer was stationed around the Capitol on Wednesday as a mob of Trump supporters breached the Capitol.

The police officer is now the fifth person to die as a result of the day’s violence. One woman was shot and killed by Capitol Police as the crowd breached the building and three others suffered medical emergencies that proved fatal.

News of the officer’s death came minutes after US Capitol Police Chief Steven Sund resigned from his position.

The announcement of Sund’s resignation came Thursday evening after U.S. House Speaker Nancy Pelosi (D-Calif.) and the president of the Capitol Police Officer’s Union both called for him to step down.

Also, at the same time, President Trump released a recorded message condemning the violence, calling for unity and vowing a peaceful transition of power.
