Federal prosecutors probing Donald Trump’s role in the attack on the U.S. Capitol have sent a grand jury subpoena to the National Archives asking for all the documents it provided to the House January 6 committee. This comes amid reports the U.S. Secret Service failed to inform Capitol Police about a threat made against Speaker Nancy Pelosi until after the January 6 attack was underway. That’s according to a new report by the watchdog group Citizens for Responsibility and Ethics in Washington, which cited email communications between law enforcement officials around the time of the insurrection.
