On Jan. 6, 2021, a mob of angry Donald Trump supporters stormed the U.S. Capitol in an attempt to stop lawmakers from certifying Joe Biden's presidential win.
Watch the video above for more on the story.
Here's a timeline of what happened on Jan. 6.
Trump took the stage at a "Save America" rally near the Capitol to spout false election fraud claims.
About 10,000 his supporters gathered as Trump stated, "They rigged the election, they rigged it like they've never rigged an election before." After a nearly hour long speech, Trump tells the crowd, "and if you don't fight like hell, you're not going to have a country anymore."
Inside the Capitol building, the House and Senate gathered for a joint session to count the votes and certify Biden's presidential win. By that point, rioters have already gathered outside.
In their first challenge, Republican lawmakers objected to Arizona's Electoral College votes cast in favor of Biden. The riots outside the building escalated.
Rioters broke into the Senate side of the Capitol. Mike Pence and lawmakers were evacuated to safety.
Capitol Police Chief J. Thomas Manger made the first call for assistance.
Rioters broke into the House side of the Capitol where some lawmakers remained trapped. Security guards stood at entrances with guns drawn.
At this point, Trump takes to Twitter writing, "Mike Pence didn't have the courage to do what should have been done to protect our Country and our Constitution ... USA demands the truth!" And a few minutes later writing, "Please support our Capitol Police and Law Enforcement. They are truly on the side of our Country. Stay peaceful!"
The violence continued for hours — rioters and police officers clashed, people roamed the halls of the U.S. Capitol building and people ransacked lawmakers' offices.
Trump posted a video to Twitter — first repeating false election fraud claims — then telling followers, "Go home and go home in peace."
National Guard members arrived at the Capitol and started moving rioters out of the scene.
The Capitol was declared safe and Congress continued the Electoral College certification process.
4 a.m., Jan. 7.
Shortly before 4 a.m., Joe Biden was declared the winner of the presidential election.
