The mob's advance forced Goodman to retreat up the stairs, but the footage shows him shouting "second floor" into his radio, alerting his colleagues that the mob was getting closer to the Senate.
Goodman took another stand against the mob at the top of the steps, where he briefly turned to his left and saw that the main entrance to the chamber was not completely secure.
"As Trump's fascist mob ransacked the US Capitol, this courageous USCP officer kept murderous rioters away from the Senate chamber and saved the lives of those inside", U.S. Representative Bill Pascrell tweeted.
As Goodman held them back, the Post reported, police were trying to lock down more than a dozen doors that led to the chamber and the galleries above.
"It makes me sick to my stomach to see that video", Contee told reporters. Armed with a baton and his training, Goodman used himself - and possibly his identity as a Black man, since some rioters carried Confederate battle flags - to bait them away from the corridor, likely saving lives.
Goodman's actions are being hailed on social media as heroic, with New Jersey Representative Bill Pascrell tweeting he "kept murderous rioters away from the Senate chamber and saved the lives of those inside". "God bless him for his courage".
The man who led the group in chasing Goodman, Doug Jensen of Des Moines, Iowa, was arrested on Saturday and faces several charges including obstructing a law enforcement officer during a civil disorder, violent entry and disorderly conduct in a Capitol building, parading, demonstrating, or picketing in a Capitol building.
According to Washington D.C. station WUSA, Goodman is an Army veteran who served in Iraq.
