Aftermath of the January 6 United States Capitol attack

The January 6 United States Capitol attack was followed by political, legal, and social repercussions. The second impeachment of Donald Trump, who was charged for incitement of insurrection for his conduct, occurred on January 13. At the same time, Cabinet officials were pressured to invoke the 25th Amendment for removing Trump from office. Trump was subsequently acquitted in the Senate trial, which was held in February after Trump had already left office. The result was a 57–43 vote in favor of conviction, with every Democrat and seven Republicans voting to convict, but two-thirds of the Senate (67 votes) are required to convict. Many in the Trump administration resigned. Several large companies announced they were halting all political donations, and others have suspended funding the lawmakers who had objected to certifying Electoral College results. A bill was introduced to form an independent commission, similar to the 9/11 Commission, to investigate the events surrounding the attack; it passed the House but was blocked by Republicans in the Senate. The House then approved a House "select committee" to investigate the attack. In June, the Senate released the results of its own investigation of the attack. The event led to strong criticism of law enforcement agencies. Leading figures within the United States Capitol Police resigned. A large-scale criminal investigation was undertaken, with the Federal Bureau of Investigation (FBI) opening more than 1,200 case files. Federal law enforcement undertook a nationwide manhunt for the perpetrators, with arrests and indictments following within days. Over 890 people had been found guilty of federal crimes.

Trump was suspended from various social media sites for his involvement in inciting the attack, at first temporarily and then indefinitely. In response to posts by Trump supporters in favor of the attempts to overturn the election, the social networking site Parler was shut down by its service providers. Corporate suspensions of other accounts and programs associated with participating groups also took place.

The inauguration week was marked by nationwide security concerns. Unprecedented security preparations for the inauguration of Joe Biden were undertaken, including the deployment of 25,000 National Guard members. In May, the House passed a $1.9 billion Capitol security bill in response to the attack.

In the days following the attack on the Capitol, Republican politicians in at least three states introduced legislation creating new prohibitions on protest activity.

Trump has publicly embraced and celebrated the January 6 Capitol attack and has made it a cornerstone of his 2024 presidential campaign. Trump has promoted a revisionist history of the event by downplaying the severity of the violence and calling those charged for their involvement in the attack "hostages."
