On January 6, 2021, following the defeat of U.S. President Donald Trump in the 2020 presidential election, a mob of his supporters attacked the United States Capitol Building in Washington, D.C. The mob sought to keep Trump in power by preventing a joint session of Congress from counting the electoral college votes to formalize the victory of President-elect Joe Biden.

According to the House select committee investigating the incident, the attack was the culmination of a seven-part plan by Trump to overturn the election.

Five people died either shortly before, during, or following the event: one was shot by Capitol Police, another died of a drug overdose, and three died of natural causes. Many people were injured, including 138 police officers. Four officers who responded to the attack died by suicide within seven months.

As of July 7, 2022, monetary damages caused by attackers exceed $2.7 million.
