DENVER (KDVR) - Five years after a crowd of President Donald Trump's supporters descended on the U.S. Capitol on Jan. 6, 2021, to protest Congress confirming President Joe Biden's 2020 election victory, several members of Colorado's congressional delegation who were in the building are reflecting on that day.

The crowd battled Capitol police to enter the building as members of Congress fled, and years later, Democrats and Republicans don't agree on a shared history of the attack. Democrats are planning a hearing with witnesses to the events of that day, while Republicans are meeting behind closed doors to talk policy for the upcoming year.

Colorado's Democratic house members, who were at the Capitol the day of the attack, also shared their thoughts five years later.

Here's what they said.

Rep. Diana DeGette

"Five years ago today, Donald Trump incited a violent mob to storm the Capitol in an attempt to overturn a free and fair election - the most brazen attack on our own government by a sitting president in American history.

"I was in the House gallery that day, and I will never forget how I felt watching the anger and chaos that Donald Trump stoked erupt across Congress. It is unconscionable that one of Trump's first acts of his second term was to pardon insurrectionists who assaulted police officers and hunted for lawmakers in the Capitol. Those convicted individuals weren't 'peaceful' or 'patriots,' as he called them, they were domestic terrorists.

"This anniversary reminds us we must never take democracy for granted."

Rep. Joe Neguse

"Five years ago, on Jan. 6th, our Capitol - and our republic - were attacked.

"Let us never forget the brave law enforcement officers who put their lives on the line to defend our democracy."

Rep. Brittany Pettersen

"Today marks five years since the violent attack on the US Capitol - one of the darkest days in our nation's history.

"Our democracy was tested and persevered. Free and fair elections, the peaceful transfer of power, & a representative democracy are not guaranteed. It will continue to take all of us fighting to preserve the rule of law, our constitution, and the promise of our country."

Rep. Jason Crow

As well as a statement, Crow on Tuesday announced he was also introducing legislation to designate Jan. 6 as "Democracy Day."

"January 6th was a violent assault on our democracy and one of the darkest days in American history. I will never forget being trapped in the House Gallery as a mob of President Trump's supporters stormed the Capitol and tried to stop the certification of a free and fair presidential election. No matter how many years go by, we cannot forget the events of January 6, 2021. Democracy Day would ensure that every American works to defend our democracy, protect free and fair elections, and ensure the peaceful transfer of power."

Sen. Michael Bennet

"Five years ago, a violent mob stormed the U.S. Capitol to try to stop the certification of a free and fair election. The legacy of that attack lives on as President Trump lawlessly undermines our Constitution at every turn.

"Today, we're reminded that we cannot take our democracy for granted and must never stop defending it."

Sen. John Hickenlooper

"President Trump provoked a violent riot against our Capitol five years ago today. Five police officers lost their lives defending our country. Trump turned around and pardoned the violent insurrectionists.

"January 6th was a stain on our history."

Meanwhile, none of the four GOP representatives from Colorado, Lauren Boebert, Gabe Evans, Jeff Hurd or Jeff Crank, have made public statements Tuesday about Jan. 6, 2021.

President Trump in one of his first actions after returning to the White house last year made a sweeping pardon of the 1,500 defendants charged in the Capitol attack.

Some of those defendants, including former Proud Boys militia leader Enrique Tarrio, held a march on Tuesday retracing the rioters' step as they went from the White House to the Capitol on Trump's calls. The march was intended to honor Trump supporter Ashli Babbitt, who died during the attack, and Babbitt's mother attended Tuesday's march.

Trump in Tuesday's GOP agenda meeting shifted blame for Jan. 6 onto the rioters themselves, the Associated Press reported.

The president said he had intended only for his supporters to go "peacefully and patriotically" to confront Congress as it certified Biden's win.
