The January 6, 2021, attack on the U.S. Capitol disrupted the certification of the 2020 presidential election, which Joe Biden won. A mob of supporters of Pres. Donald Trump stormed the Capitol, aiming to prevent the legitimate president-elect from assuming office. This event was widely regarded as an insurrection and an act of domestic terrorism.
The attack led to the second impeachment of Donald Trump for inciting violence against the government. He was acquitted by the Senate. It also resulted in approximately $1.5 million in damage to the Capitol building. In the aftermath, many individuals were arrested and charged with federal crimes. With his January 2025 inauguration to a second term, Trump issued pardons and commutations to many of those found guilty of participating in the attack.
