Sen. Andy Kim (D-N.J.), who famously cleaned up trash after the Jan. 6, 2021, attack on the Capitol, said he is concerned that day is being “papered over.”

Kim joined CNN’s Dana Bash on Sunday for “State of the Union” and reflected on that day as it nears the four-year anniversary.

“I mean, we saw with our own eyes — those of us that were in Congress, the American people saw, people all over the world saw. And the idea that it’s being papered over and that people that attacked the Capitol rioted, that they’re being talked as liberators, as prisoners now that are being unfairly treated,” Kim said, as highlighted by Mediaite.

“We are a nation of rule of law and it … does break my heart,” he continued.

Kim, who represented New Jersey in the House since 2019, was elected to the Senate in November and took over the seat early from George Helmy (D), who had been appointed to replace Bob Menendez (D).

As President-elect Trump prepares to take office again, there are concerns about what, if any, emboldened actions he, his administration and his supporters may take.

Trump has vowed to seek retribution against his political enemies, including those who sat on the Jan. 6 House committee to investigate his role in the attack.

Kim said that it makes him sad that rioters caused destruction in the Capitol and attempted to overturn the 2020 election results.

“This nation is such a great nation, and we were brought to such a sad moment on that day,” he said. “We should commit ourselves to never letting that happen again. But, instead, we see that, unfortunately, being a different lesson that many are taking away.”
