The U.S. Capitol’s top operations official told Congress on Wednesday more than $30 million will be needed to repair the building after the deadly Jan. 6 riot.

That includes repairing statues and works of art damaged in the violence, as well as providing increased security and mental health services to the staff, said J. Brett Blanton, the architect of the Capitol.

“The events of Jan. 6 were difficult for the American people and extremely hard for all of us on campus to witness,” Blanton told the House Appropriations Committee, according to The New York Times.

Blanton said the committee had already approved the transfer of $30 million to maintain the temporary fencing around the Capitol complex through March 31 and support National Guard troops stationed in the building. But he said more funds would most likely be needed to address the intensified security and support.

Farar Elliott, the House curator, requested $25,000 for emergency repair and conservation of objects in the House collection, the Times reported.

Also Wednesday, the acting chief of Capitol Police said her department knew armed extremists were primed for violence at the iconic building on Jan. 6 and even provided officers with assault rifles to protect lawmakers. But the riot was far worse than police expected, leaving them unprepared to fight it off.

A day earlier, her predecessor as chief testified that police expected an enraged but more typical protest crowd of Donald Trump supporters. But Acting Chief Yogananda Pittman said intelligence collected ahead of the riot prompted the agency to take extraordinary measures, including the special arming of officers, intercepting radio frequencies used by the invaders and deploying spies at the Ellipse rally where President Donald Trump was sending his supporters marching to the Capitol to “fight like hell.”

Pittman’s testimony, submitted ahead of a House hearing Thursday, provides the most detailed account yet of the intelligence and preparations by U.S. Capitol Police ahead of the insurrection when thousands of pro-Trump rioters invaded the Capitol aiming to stop Congress from certifying Joe Biden’s election victory over Trump.

Three days earlier, on Jan. 3, Capitol Police distributed an internal intelligence assessment warning that militia members, white supremacists and other extremist groups were likely to participate, that demonstrators would be armed and that it was possible they would come to the Capitol to try to disrupt the vote, Pittman says.

“Based on the assessment, the Department understood that this demonstration would be unlike the previous demonstrations held by protesters with similar ideologies in November and December 2020,” Pittman says in her prepared remarks.

But, at the same time, she argues police didn’t have enough intelligence to predict the violent insurrection that resulted in five deaths, including that of a Capitol Police officer. They prepared for trouble but not an invasion.

“Although the Department’s January 3rd Special Assessment foretold of a significant likelihood for violence on Capitol grounds by extremists groups, it did not identify a specific credible threat indicating that thousands of American citizens would descend upon the U.S. Capitol attacking police officers with the goal of breaking into the U.S. Capitol Building to harm Members and prevent the certification of Electoral College votes,” Pittman says in her testimony.

Steven Sund, the police force’s former chief who resigned after the riot, testified Tuesday that the intelligence assessment warned white supremacists, members of the far-right Proud Boys and leftist Antifa were expected to be in the crowd and might become violent.

“We had planned for the possibility of violence, the possibility of some people being armed, not the possibility of a coordinated military style attack involving thousands against the Capitol,” Sund said.

The FBI also forwarded a warning to local law enforcement officials about online postings that a “war” was coming. But Pittman said it still wasn’t enough to prepare for the mob that attacked the Capitol.

Officers were vastly outnumbered as thousands of rioters descended on the building, some of them wielding planks of wood, stun guns, bear spray and metal pipes as they broke through windows and doors and stormed through the Capitol. Officers were hit with barricades, shoved to the ground, trapped between doors, beaten and bloodied as members of Congress were evacuated and congressional staffers cowered in offices.
