The Trump administration asked the Supreme Court to order California to set aside more than 20,000 ballots cast by voters who, according to the executive branch's review, are likely not US citizens, a day before the midterm elections.

The request says the executive branch identified more than 20,000 people registered in California based on publicly accessible information. On Friday, a divided panel of the US Court of Appeals for the 9th Circuit turned aside the administration's emergency request to segregate the ballots.
