oseph Fischer spent about four minutes inside the capital building on Jan. 6th, and was charged with seven criminal charges, including a felony count of obstructing an official proceeding. Fischer has pleaded not guilty and is awaiting trial, but first his case will be heard at the Supreme Court, which on Tuesday will consider his claim that the obstruction of Congress charge is illegitimate. If the court agrees, it could reverse hundreds of Jan. 6 prosecutions—including Trump’s.
