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."

In an interview with ABC News Live on Thursday, Maryland Democratic Rep. Jamie Raskin reflected on the whirlwind period between the death of his 25-year-old son and Trump's second impeachment trial following the attack.

Raskin's son, Tommy Raskin, died by suicide on New Year's Eve 2020. The day after his son was buried, Raskin was on Capitol Hill when Trump supporters stormed the Capitol.

"The day after we buried Tommy in a small family COVID-19 graveside service, we had the violent insurrection at the Capitol and the attempt to overthrow the 2020 presidential election by Donald Trump," said Raskin, who wrote about the experience in his new book, "Unthinkable: Trauma, Truth, and the Trials of American Democracy."

"I felt like I had an obligation to do it, that Tommy would be completely with me the whole way," Raskin said. "And this was a chance to try to stand up and articulate, not just my love, but our family's love, of our Constitution and our freedom and our democracy and the idea of human rights -- the opposite of everything that was on display on Jan. 6."

Raskin is a member of the Jan. 6 House select committee tasked with investigating the attack. To date, the committee has issued at least 50 subpoenas to individuals for information, according to an ABC News count, with at least 19 of those being Trump administration officials. It has conducted more than 300 depositions.

Five people died during or after the riot, including four protesters and one law enforcement officer. Separately, four officers who responded to the riot have died by suicide.

Approximately 140 police officers were injured the day at the Capitol including about 80 U.S. Capitol Police and about 60 from the Metropolitan Police Department, according to the Justice Department. Lawmakers on Thursday praised the group for holding the line and protecting the Capitol from even more bloodshed last year.

Approximately $1.5 million in damage was done to the Capitol building, according to federal prosecutors.

"Well over 10,000" people came onto the Capitol grounds last year, according to Capitol Police, and at least 2,000 people actually entered the building. At least 706 individuals have been charged with crimes, according to an ABC News count, and approximately 150 individuals have pleaded guilty to misdemeanors.

Capitol Police Officer Brian Sicknick, who was injured while confronting the mob during the insurrection, suffered multiple strokes hours after serving on the front lines and died, was recognized several times by lawmakers on Thursday.

While leading members of Congress in sharing their reflections, Rep. Jason Crow, D-Colo., called attention to Sicknick’s parents who were present in the caucus room, asking them to stand and be recognized.

"For those of you joining us at home, Brian Sicknick was an officer who gave his life on Jan. 6, 2021, in defense of this Capitol and in defense of many of us," Crow said.

"We sit in here and owe your family a debt of gratitude that we can never repay," Crow told his parents. "We will be there for you and your family going forward, and you are now a part of our family as well."
