Jan. 6 updates: Biden tears into Trump for inciting Capitol attack

To mark one year since a violent mob of Trump supporters stormed through the Capitol -- including Statuary Hall where Biden will soon speak -- and attempted to breach the House chamber in an attempt to undo the 2020 election, in his remarks this morning, Biden will say that Americans are facing a moment when “we must decide what kind of nation we are going to be.”

“Are we going to be a nation that accepts political violence as a norm? Are we going to be a nation where we allow partisan election officials to overturn the legally expressed will of the people? Are we going to be a nation that lives not by the light of the truth but in the shadow of lies?” Biden will say according to speech excerpts released by the White House. 

“We cannot allow ourselves to be that kind of nation. The way forward is to recognize the truth and to live by it,” the excerpt read. 

While Biden is not expected to mention the former president by name, the White House said he will lay out the “singular responsibility President Trump has for the chaos and carnage that we saw.” 

Upon Biden’s arrival to the Capitol, Speaker Nancy Pelosi and Senate Majority Leader Chuck Schumer greeted him. The pair flanked the president as they walked towards Statuary Hall.

Armored military vehicles, concertina wire atop non-scalable fencing and the massive show of force that fortified Capitol Hill in the aftermath of the violent attack on democracy last Jan. 6 are not defining Thursday's anniversary.

The security posture in Washington, by comparison, appears fairly ordinary. The temporary fencing that ringed the Capitol for more than six months, and again briefly for a September demonstration has not returned, though that could change quickly if conditions warrant, Capitol Police Chief Tom Manger told ABC News Chief Justice Correspondent Pierre Thomas in a recent interview. 

In a briefing Tuesday, Manger said his office was aware of several events planned for the day but that “most of them aren't of much concern to us.”

“There's no intelligence that indicates that there would be any problems,” he said.

At least 704 accused rioters have been charged by the Department of Justice, according to an ABC News count. At least 172 have pleaded guilty to their changes.

The FBI is still seeking 350 individuals believed to have committed violent acts on the Capitol grounds, according to the DOJ, including over 250 who assaulted police officers.

The union representing United States Capitol Police officers praised the "dedication and commitment" of those who protected the Capitol building one year ago.

"Today, we recognize the dedication and commitment to mission of the men and women who put their own lives and safety on the line to defend the U.S. Capitol," Gus Papathanasiou, chair of the union, said in a statement Thursday. "We especially pay tribute to Officer Sicknick who died after being injured during the rioting, and to Officer Liebengood who tragically took his own life after the attack."

According to Papathanasiou, 80 Capitol Police officers sustained injuries that day, with some so serious they are still not back at work. He said members of the force remain "committed to our mission," but that comes with an increase in officers as well as improved intelligence and communications between officers and leadership.

Papathanasiou noted that the legacy of Jan. 6 -- from a policing perspective -- should be a police force that is better prepared, with an eye toward readiness if an attack of such scale ever occurred again.

"Going forward, this Union will work with the Department to ensure those sacrifices will not be in vain," he added. "We must ensure that the events of January 6th are never repeated."
