Federal prosecutors are adjusting plea deals and dropping obstruction charges against some January 6 rioters following a Supreme Court ruling that limited the charge's application. Among those affected are members of groups like the Proud Boys, with prosecutors offering alternative deals or dismissing the obstruction charge. The Justice Department aims to hold rioters accountable within legal boundaries set by the court's decision, impacting around 259 defendants facing obstruction charges. Prosecutors must now connect defendants to specific actions related to impeding official proceedings to proceed with charges, leading to potential dismissal for some accused individuals. This shift reflects ongoing legal developments post the Supreme Court's decision on obstruction charges in the context of the Capitol riot cases.
