Monday marks the fourth anniversary of the violent events of Jan. 6, 2021 — a day President-elect Donald Trump has continually tried to recast as a “day of love.”

Trump is vowing to pardon Jan. 6 rioters on the first day of his administration, saying while it will done be on a case-by-case basis, he believes a majority of them should not be in jail and have “suffered greatly.”

At an event at Mar-a-Lago over the weekend, according to an audio recording obtained by ABC News, he continued to claim that the the electoral votes from the 2020 election “could have been sent back” and criticized then-Vice President Mike Pence for adhering to his constitutional duty to uphold the certification process and not unilaterally reject the election results.

President Joe Biden, on the other hand, penned an op-ed on Sunday in which he pushed back on attempts to “rewrite — even erase — the history of that day.”

“Violent insurrectionists attacked the Capitol, threatened the lives of elected officials and assaulted brave law enforcement officers,” he wrote in the Washington Post. “We should be proud that our democracy withstood this assault. And we should be glad we will not see such a shameful attack again this year.”

And in remarks to congressional Democrats, Biden said it was now their “duty to tell the truth.”

“You remember what happened, and don’t let Jan. 6 be rewritten or even erased,” he told them. “To honor the Constitution, not only the most extraordinary of days, but it’s one of the toughest days in American history: Jan. 6.”

On the campaign trail, Trump often aired grievances and false claims about the 2020 election and tried to downplay what transpired on Jan. 6, 2021.

One notable exchange came during a Univision town hall weeks before Election Day, when a Republican audience member pressed Trump on his actions that day as thousands of his supporters stormed the U.S. Capitol, temporarily disrupting the certification of Biden’s win.

Trump falsely claimed no one in the crowd was carrying firearms.

“That was a day of love,” Trump said. “From the standpoint of the millions, it’s like hundreds of thousands. It could have been the largest group I’ve ever spoken to before. They asked me to speak. I went and I spoke, and I used the term ‘peacefully and patriotically.'”

During the ABC News presidential debate in September 2024, Trump was asked if he had anything he regretted about Jan. 6, 2021.

“I had nothing to do with that, other than they asked me to make a speech,” he responded.

Nearly 1,600 individuals have faced charges associated with the Capitol attack, according to new figures released by the U.S. Attorney’s Office.

That includes 608 individuals who have faced charges for assaulting, resisting or interfering with law enforcement trying to protect the complex that day, the office said. Approximately 140 law enforcement officers were injured during the riot, the DOJ has said.

On Monday, Vice President Kamala Harris will preside over the congressional certification of Trump’s 2024 victory.

In a brief video message on Monday, Harris reflected on the importance of the peaceful transfer of power, saying the country’s witnessed how “our democracy can be fragile” and “it is up to then each one of us to stand up for our most cherished principles.”

Trump on social media called the upcoming certification a “A BIG MOMENT IN HISTORY. MAGA!”
