House Speaker Nancy Pelosi on Thursday called for the resignation of the US Capitol Police chief and informed the House Sergeant-at-Arms has told her he is submitting his resignation after criticism over an apparent lack of preparedness to deal with Wednesday’s violent mob on Capitol Hill.

Pelosi’s statements follow Senate Democratic Leader Chuck Schumer who said he would fire the current Senate Sergeant-at-Arms when he becomes majority leader.

“If Senate Sergeant Arms Stenger has not vacated the position by then, I will fire him as soon as Democrats have a majority in the Senate,” Schumer said in a statement.

Michael C. Stenger, appointed by Senate Majority Leader Mitch McConnell, was expected to be eventually replaced when the chamber flipped to Democrats. However, Schumer has made it clear Stenger either needs to resign or be fired in the wake of the harrowing events that transpired, part of the growing reaction to the mob that stormed Capitol Hill.

On Thursday, Capitol Police leadership provided first details about the deadly incident that left lawmakers and staff fearful for their lives.

In a statement released Thursday morning, chief of police Steven A. Sund detailed the violent actions of the rioters saying that Capitol Police and other law enforcement officers were “actively attacked” with metal pipes and other weapons, CNN reported.

“The violent attack on the U.S. Capitol was unlike any I have ever experienced in my 30 years in law enforcement here in Washington, DC,” Sund said. “Maintaining public safety in an open environment — specifically for First Amendment activities — has long been a challenge.”

Lawmakers have been baffled by the lack of preparedness among law enforcement given that it had been known for weeks that President Donald Trump was promoting a rally he said was aimed at preventing the certification of Joe Biden’s win.

However, Representative Mike Quigley, an Illinois Democrat who was locked in the House chamber during an armed standoff between Capitol Police and a rioter, praised the officers who were in the building that put their lives on the line to protect the lawmakers.

But Quigley made clear that they were outnumbered and law enforcement was underprepared.

“The Capitol Police I was around did an amazing job under difficult circumstances,” Quigley told CNN.

“My concern wasn’t with how valiant the Capitol Police were. It was that an hour before the debate started, I looked at the throngs of people surrounding different sections of the Capitol — and said, we don’t have enough security.”

Quigley added: “I’m no expert in security, but you can tell we were out-manned in an hour before the debate,” referring to Congress’ proceedings to certify Biden’s win.
