"I never expected today to be quite as emotional for me as it has been," Kinzinger said, sniffling as he took back tears. He shows he got to know many of the officers as a result of the riot.
Both he and Cheney embraced each other with a few of the officers at the beginning of the hearing.
"I think it's important to tell you right now though," Kinzinger continued. "You guys may, individually, feel a little broken." But, he added: "You guys won."
The touching day got to almost everyone - lawmakers and witnesses as one. Several times the officers rubbed away tears, especially when footage from January 6th was shown. The lawmakers got rocked up talking about their appreciation for the officers' work.
"You saved the day. You saved the Constitution," Rep. Zoe Lofgren told them.
Some of the most moving words came early on when Cheney, in her opening statement, offered cautionary words about what could happen in the wake of future presidential elections. She called January 6th a "cancer" on the Constitution.
"If those responsible are not held accountable and if Congress does not act responsibly, this will remain a cancer on our constitutional republic, undermining the peaceful transfer of power at the heart of our democratic system. We will face the threat of more violence in the months to come and another January 6 every four years," she said.
Six months after the occurrence, where Donald Trump radical advocates breached the Capitol to try and stop the certification of Joe Biden's presidential victory, 590 people have been accused. More than 300 suspects are still wanted by law enforcement. As a result of that day, five people died while staff and officers on Capitol Hill remained traumatized over what happened.
The committee began its first hearing on January 6th with dramatic new footage from that day, noting Trump's supporters invading the building and attacking police officers.
It also included disturbing testimony from four offices at the Capitol that day, who reported being physically struck by the rioters, being insulted, and fearing for their lives.
"We are not asking for medals and recognition, we just want justice and accountability," said Sgt. Aquilino Gonell of US Capitol Police.
And Officer Daniel Hodges of the DC Metropolitan Police told the seven Democrats and two Republicans on the board what he wanted of them was to find out "if anyone in power had a role in this, anyone in power coordinated or aided or abetted or tried to downplay or tried to prevent the investigation of this terrorist attack, because we can't."
