WATCH: U.S. Capitol Police chief give remarks on Capitol security ahead of Jan. 6 anniversary

Chief of the Capitol Police said his force is “stronger and better prepared to carry out its mission today than it was before January 6th of last year.”

The department began significant work immediately after January 6 to “fix the failures that occurred: intelligence failures, operational planning failures, leadership failures,” said Chief Tom Manger.

“The one thing that did not fail that day was the courage and resolve of the men and women of United States Capitol Police,” he said.

Manger’s comments come just days before the one year anniversary of thousands of violent pro-Trump rioters overwhelming police officers at the U.S. Capitol, severely injuring dozens in the process.

The leaders who were in charge of the U.S. Capitol Police on Jan. 6 were ousted following criticism for intelligence and other failures that left the legislative branch vulnerable to the stunning attack.

And more broadly, the agency that was once little-known outside of Washington now has an elevated profile, leading to a roughly 15 percent increase in funding and a greater awareness of its role in the patchwork of groups that protect the region.

With the nation’s political divide running deep and an unprecedented number of threats against lawmakers, there is still concern about the readiness of the Capitol Police to thwart another attack.

The Capitol Police Board has oversight of the force and is comprised of the House and Senate sergeants-at-arms and the architect of the Capitol, who oversees the building.

After numerous reports the Board said they were offered over 100 recommendations and have completed about 90 of them

“There was no question in my mind looking at all of the recommendations that intelligence, operational planning and getting… our civil disturbance unit up to where it needs to be were the three biggest issues,” said Manger.

“And those were the ones that we worked on first, and those are the ones that frankly are largely completed.”

The police department had compiled numerous intelligence documents suggesting the crowd could turn violent and even target Congress last year.

The intelligence documents, obtained by The Associated Press, warned that crowds could number in the tens of thousands and include members of extremist groups like the Proud Boys.

In the last year, Capitol Police say they have also improved the way that investigators gather, analyze and disseminate intelligence and have brought on someone dedicated to planning major events to focus on intelligence and coordination.

The agency has also started conducting planning sessions and exercises ahead of major events and is briefing officers in person.

Many officers within the department had criticized their own leaders, saying they had failed to recognize the threat ahead of the insurrection and didn’t do enough to bolster staffing.

Some officers were outfitted with equipment for a protest, rather than a riot.
