The shattered glass panes on the doors to the U.S. Capitol Rotunda from the East Front -- known as the Columbus Doors -- were replaced with new glass Thursday after sustaining damage during the Jan. 6 riot, according to the Architect of the Capitol's office.

"Moving forward, we are looking at options to display a collection of items from Jan. 6," spokesperson Laura Condeluci told ABC News.

The shattered glass was in place during Biden's inauguration, and he could be seen walking past the panes.

Lawmakers have discussed various ways to display the glass and other vestiges of the attack around the Capitol.

"It would be a good thing to preserve some evidence of the destruction of the building. So that 150 years from now, as people tour the building, they'll say, 'Ah, this was where that insurrection occurred,'" Sen. Mitt Romney told ABC News recently.

The Senate has returned from a roughly 35-minute break to resume arguments from the House impeachment managers.

David Schoen, a member of Trump's legal defense team, appeared on Fox News during the Senate trial. Schoen argued that it will not help healing to "show and reshow" the tragedy of the Jan. 6 riot.

"I have always said that this trial never should have happened, and if it happened, it should be as short as possible given the complete lack of evidence and the harm that this is causing to the American people," Schoen said.

As the House managers continue to lay out their allegations, Schoen offered an assessment of Trump's mood.

"The president is very upbeat, he has condemned the violence, and doesn't in any way want to be associated with what happened in this violent incident," Schoen said. "He has condemned the people involved and obviously quite offended at being tied into it."

Schoen told reporters that he thinks the House managers are "making a movie," saying they haven't "in any way" tied the riots to Trump.

Rep. David Cicilline, D-R.I., in focusing his arguments on the harm inflicted inside Capitol walls on Jan. 6, noted the terror aimed particularly toward people of color at the complex.

"For many of the Black and brown staff, the trauma was made worse by the many painful symbols of hate that were on full display that day. Insurrectionists waved Confederate flags and hurled the most disgusting racial slurs at dedicated Capitol workers," he said.

"Then after all that, these same workers -- many of them people of color -- were forced to clean up the mess left by mobs of white nationalists," Cicilline continued.

He recalled how one member of the Capitol janitorial staff reflected on "how terrible he felt when he had to clean up feces that had been smeared on the wall, blood of a rioter who had died, broken glass, other objects, strewn all over the floor. He said, 'I felt bad. I felt degraded.'"

A mural paying tribute to civil rights icon, the late Rep. John Lewis, D-Ga., was "shamefully destroyed," Cicilline said, and "only a broken piece of the memorial was found on the ground next to a trash can," he said.

Quoting an article from Buzzfeed, Cicilline recalled two Black police officers saying they were called racial slurs repeatedly as they fought off white nationalists on Jan. 6.

"Is this America? What is your answer to that question? Is this OK? If not, what are we going to do about it? These people matter. These people risked their lives for us. So I ask you respectfully to consider them -- the police officers, the staff of this building -- when you cast your vote," Cicilline said.

After the Senate decided it will not call any witnesses, lead House manager Rep. Jamie Raskin, D-Md., was the first to speak during closing arguments. He reiterated the prosecution's case, calling for the conviction of Trump.

"It was suggested by defense counsel that Donald Trump's conduct during the attack, as described in Congresswoman Beutler's statement, is somehow not part of the Constitutional offense for which former President Trump has been charged," Raskin began. "I want to reject that falsehood and that fallacy immediately. After he knew that violence was underway at the Capitol, President Trump took actions that further incited the insurgents to be more inflamed and to take even more extreme, selective, and focused action against Vice President Mike Pence."

Raskin went on to use his time to describe Trump's months-long campaign to discredit the 2020 election results by spreading misinformation, which he argued laid the groundwork for deadly events of Jan. 6. He went on to claim that the former president assembled the mob, incited it and then sent it off to the Capitol during his speech. At every point, Trump sided with the insurrectionists rather than the Congress, Raskin said.

Once when the violence began, Raskin declared that Trump ignored the violence and further incited it by aiming the attacks on his own vice president.

"There has never been a greater betrayal by the president of the United States of his office, and of his oath to the Constitution."

Raskin then took a moment to suggest the GOP used "cancel culture" against one of its leaders, Rep. Liz Cheney, R-Wyo., who voted to impeach Trump in the House.

"Liz Cheney is a hero for standing up for the truth, and resisting this retaliatory cancel culture that she was subjected to."

Raskin emphasized his gratitude toward the Capitol Police, and finished his argument by saying convicting Trump is a vote for the "security of our democracy."

"They attacked this building, they disrupted the peaceful transfer of power, they injured and killed people, convinced that they were acting on his instructions, and with his approval, and protection," Raskin finished. "And while that happened, he further incited them, while failing to defend us. If that's not ground for conviction, if that's not a high crime and misdemeanor against the republic in the United States of America then nothing is. President Trump must be convicted for the safety and security of our democracy and our people."
