Arriving on Capitol Hill, reporters asked the president ahead of his remarks how he was feeling heading into the day.

The president, flanked by House Speaker Nancy Pelosi and Senate Majority Leader Chuck Schumer, appeared to respond, "Praying that we will never have a day like we had a year ago today."

Notably, he did not respond when asked if he held Trump personally responsible for the attack.

The three walked towards Statuary Hall, which rioters stormed through one year ago.

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.

Biden took the oath of office just days after the violent attack on the Capitol last Jan. 6, but he has fastidiously tried to prevent those unprecedented circumstances -- or his predecessor -- from dominating his first year in the White House.

But on the anniversary of the insurrection, he confronted Trump in a direct, personal way, in some of his strongest language yet.

"We must be absolutely clear about what is true and what is a lie. And here's truth," he said, speaking from Statuary Hall in the Capitol that rioters ransacked last year. "The former president of the United States of America has created and spread a web of lies about the 2020 election. He's done so because he values power over principle. Because he sees his own interest as more important than his country's interest -- than America's interest -- and because his bruised ego matters more to him than our democracy or our Constitution. He can’t accept he lost."
