Rep. Matt Gaetz (R-Fla.) on Monday, Feb. 15, said he wanted to see the surveillance footage regarding the death of Capitol Police Officer Brian Sicknick during the breach of the U.S. Capitol on Jan. 6.

Sicknick, a longtime officer with Capitol Police, died on Jan. 7, one day after the riot. According to early media reports, Sicknick died after being hit in the head with a fire extinguisher. However, more than a month after the incident, the Washington, D.C. medical examiner’s office has not yet revealed the cause of his death.

Fox News contributor Jason Chaffetz, speaking on Fox News’ Hannity Monday evening, raised 13 security-related questions for House Speaker Nancy Pelosi (D-Calif.). In an op-ed for Fox News alongside Chaffetz, Gaetz told Hannity he would add another question to Chaffetz’s list regarding security cameras around the Capitol Building, Newsweek reported. 

“I want to know precisely what happened to cause the death of Officer Brian Sicknick,” Gaetz said. “I mean, the Capitol complex has more surveillance than a casino, and you’re telling me we don’t have any video evidence of what exactly happened to cause that murder? I want to know.”

According to D.C. police, five other people died following the riot, including a woman who was fatally shot by a Capitol Police officer and four others who died after suffering medical emergencies. The riot prompted a Democratic-led impeachment against former President Donald Trump for “incitement of insurrection.” Trump was acquitted in the Senate trial on Saturday.

Separate to Gaetz’s demand, several congressional Republicans sent a letter earlier Monday pressing Pelosi for answers about issues related to the Jan. 6 breach of the U.S. Capitol building.

In their letter to Pelosi, Reps. Jim Jordan of Ohio, Rodney Davis of Illinois, James Comer of Kentucky, and Devin Nunes of California, say that “many important questions about your responsibility for the security of the Capitol remain unanswered” more than a month since the incident.

“Preservation and production requests were sent to the [Sergeant at Arms] SAA and the House Chief Administrative Officer, among other legislative agencies, requesting that such relevant information concerning the attack on the Capitol … be preserved and produced to the relevant committees,” they wrote. “In multiple cases, your appointees, acting on your behalf, have denied requests to produce this information.”

“Even more troubling is despite your House Officers’ refusal to comply with the request, we have recently learned that some of the same material we requested was provided to the House Judiciary Committee on a partisan basis. This is unacceptable. Madam Speaker, that direction could only have come from you,” they added.

While Pelosi dodged questions about her role in the security lapses on Jan. 6, she calls for a new 9/11-style commission to further investigate the Capitol Building’s breach.
