DC Metropolitan Police Officer Michael Fanone said during his opening remarks that Jan. 6 was "unlike anything I had ever seen" in his 20 years with the MPD police.
He said that during the attack he was at risk of being stripped of and killed with his firearm. He said during the riot he heard chants of "kill him with his own gun."
"I can still hear those words in my head today," Fanone said.
Some more background: Of the hundreds of police officers who defended the Capitol on Jan. 6, none has become more outspoken than Fanone. He has met with lawmakers, publicly supported the creation of a bipartisan commission and slammed Republicans who whitewashed the violence of that day.
CNN exclusively obtained Fanone's body-worn camera footage, which shows how he was pulled into the crowd, beaten with a flagpole and repeatedly tased with his own Taser.
