 Trump sues January 6 committee. Former U.S. President Donald Trump is suing the United States House Select Committee investigating the January 6 attack on the United States Capitol in order to challenge its subpoena for documents and his testimony. Trump claims that he should be immune from such testimony about the time he was president and said it would violate privileged protections around the executive branch. His lawyer stated that the request from the committee is an unwarranted intrusion upon the institution of the presidency because there are other sources of the requested information. The attack followed the U.S. President Donald Trump's defeat in the 2020 presidential election when a mob of his supporters attacked the Capitol building in Washington DC seeking to keep Trump in power. Five people died during the attack and many more were injured including 138 police officers.
