The US Supreme Court rejected the Trump administration's emergency bid to prevent California from counting mail-in ballots from more than 20,000 voters it claims are non-citizens, ruling just hours after the request was filed. The one-sentence order came the day before the mid-term elections, without explanation and without public opposition. The U.S. Department of Justice required California to set aside the ballots until the voters' citizenships could be verified, arguing that they could not be recovered after being mixed up with others. California says the list, compiled by the U.S. Department of Homeland Security, is full of errors, and a federal judge has noted that people labeled as noncitizens in other states have repeatedly turned out to be naturalized citizens.
