The U.S. Supreme Court voted on Friday, September 25, 2026, to allow a government data system that screens voter rolls for alleged non-citizens to remain in operation, reversing a lower court order that had shut it down.

The system, which the Trump administration overhauled, draws on citizenship records and other sensitive personal data to identify people on voter rolls who may not be eligible to vote, BBC News reported. NPR said a lower court had previously found the system violated federal privacy protections before the Supreme Court stepped in to revive it.

Critics of the system have pointed to cases in which U.S. citizens were incorrectly identified as non-citizens through its screening process, according to NPR.
