3. US Supreme Court - Voter Database Ruling

A major US domestic political/legal story:

The US Supreme Court allowed the Trump administration's expanded immigration database to resume operating nationwide, overturning a lower-court order that had paused it. The emergency order allows states to use the Department of Homeland Security's Systematic Alien Verification for Entitlements program, known as SAVE, to help verify whether people on their voter rolls are eligible to vote.

Critics warn that mismatches in the database could wrongly flag eligible citizens as non-citizens, effectively purging legitimate voters from the rolls.
