The United States House Select Committee to Investigate the January 6th Attack on the United States Capitol, more commonly known as the January 6th Committee, is a bipartisan select committee of the U.S. House of Representatives investigating the January 6 United States Capitol attack. The attack was perpetrated by a mob of supporters of then-President Donald Trump, who had lost the 2020 U.S. presidential election but refused to concede, making false and disproven claims of widespread voter fraud, in an unprecedented attempt to overturn the election. The committee has received sworn testimony that Trump knew he did not win the election and contends that he was perpetrating a fraud. It has referred to a "criminal conspiracy" that led to the attack on the Capitol.
