 Live from NPR News in Washington, I'm Jack Spear. The Supreme Court handed a major victory to defendants charged in the January 6th attack on the U.S. Capitol today. As NPR's Tom Dreisbach reports, the court ruled prosecutors had improperly relied on a law against obstruction. Federal prosecutors have charged more than 300 January 6th defendants with felony obstruction of an official proceeding, basically obstructing Congress's certification of the electoral college vote.
