The Supreme Court ruled that the Trump administration can continue using a controversial data system to check voter citizenship, overturning a lower court finding that it violated federal privacy protections. Critics, including voting rights advocates, warn the system has a history of erroneously flagging U.S. citizens as noncitizens, raising fears that eligible voters could be wrongly purged from registration rolls. The ruling comes amid broader Trump administration efforts to overhaul voter verification systems ahead of the 2026 midterm elections. Civil rights groups say the decision could have wide-reaching consequences for election administration nationwide, particularly in states that rely on the database to trim voter lists.
