During a hearing before the Senate Rules Committee on Wednesday, Manger insisted that while Capitol Police "will be tested again," they will be equipped to handle it given the steps they have taken.
"I am pleased to report that we have addressed a significant portion of the many recommendations issued to the Department. In fact, of the more than 100 recommendations issued by the Inspector General, we have implemented and are addressing over 90 of them," Manger stated, referring to an inspector general's report discussing the department's shortcomings.
Manger asserted that a big reason why the riot on Jan. 6 got out of control was a "lack of a department-wide operational plan for the joint session," and that since then "a blueprint for operational planning has been created."

"If Jan. 6 taught us anything, it’s that preparation matters," Manger conceded.
Manger stressed that among those changes are an improved Civil Disturbance Unit, a new critical incident response plan, an established bicycle response team, and the inclusion of a former Secret Service official who has assisted them in planning.

"Few changes," Manger went on, "are as dramatic as the ones that we’ve made to the way we gather, analyze, share, use and disseminate intelligence."

A written statement issued to the Committee included details of measures. These include "large-scale joint exercises'' with federal law enforcement, providing cell phones to officers to improve communication, "improved and expanded training sessions for recruits, officers, and supervisors," and improvements to their public information office.

Despite Manger's claims, House Republican leadership is not necessarily convinced that the Capitol Police is ready for a future protest.
One GOP source told Fox News it is "very difficult to reconcile" what Manger is declaring publicly about security upgrades when it flies in the face with some of what has been said by Capitol Police Inspector General Michael Bolton. While Manger stated his department was "addressing" 90 of Bolton's 104 security recommendations, Republicans note that Capitol Police have yet to implement 64 of them.

The GOP source suggested that Bolton or Manger is not being truthful.
One Republican leadership source cited the continued presence of assistant chief Yogananda Pittman.
"The only people who really took the fall were [former Capitol Police Chief Steven] Sund and [former Assistant Chief] Chad Thomas," the source said, adding that Pittman is "still there" nearly a year later.

"There have been no real, meaningful changes," the source proclaimed.
One area that Manger has readily admitted needs improvement is the size of his force.
"One thing that we have not been able to fix, so to speak, are the staffing issues," Manger told "Fox News Sunday," noting that nearly a year after the riot he is still "about 400 officers short of where we need to be."
