Federal courts block Trump's travel ban after nationwide airport chaos

President Trump signed Executive Order 13769 on January 27, 2017, suspending entry from seven Muslim-majority countries and halting the refugee program. Within hours, travelers with valid visas were detained at airports across the country. Federal judges in New York, Massachusetts, and Washington issued emergency stays within days; the Ninth Circuit Court of Appeals upheld the Seattle district court's nationwide injunction on February 9, blocking enforcement of the order.
