The Supreme Court appeared deeply divided Tuesday over whether prosecutors improperly stretched federal law to charge hundreds of participants in the Jan. 6, 2021, attack on the Capitol, a decision that will impact those rioters and, potentially, Donald Trump’s election interference trial in D.C. The court’s ruling has the potential to unwind their convictions and sentences, most of which were well under 20 years, and upend the charges still pending for other defendants. Three Jan. 6 defendants have had their sentences reduced ahead of a decision by the Supreme Court. The court’s decision, expected by late June or early July, could also further delay Trump’s already stalled trial for allegedly trying to remain in power after his 2020 defeat. Two of the four charges he faces are based on the obstruction statute, and he could move to have those charges dismissed if the Supreme Court rules for the rioters.
