Supreme Court allows Trump administration to use expanded database for potential voter purges - NBC News

The justices split 6-3 along ideological lines, with conservatives in the majority, granting an emergency request from the government. Lower courts had already ruled that the administration's changes to the database were likely unlawful before the Supreme Court stepped in.

Critics argue the data is unreliable and warn it could lead to U.S. Citizens getting kicked off voter rolls by mistake. The court's unsigned ruling did note that the National Voter Registration Act bars broad purging of voters, a limit that stays in place even as the database expansion moves forward.

The decision is a win for the Trump administration. States now have access to an expanded tool for checking voter eligibility, but the fight over how that data gets used, and who might wrongly lose their registration, isn't settled.
