Travel Ban Expansions: From Muslim Ban to Permanent Entry Restrictions
The travel ban evolved through three executive orders as earlier versions were blocked by courts for discriminatory purpose and due process violations. The third version added non-Muslim-majority countries to provide legal cover, and was upheld by the Supreme Court 5-4 in June 2018. The Court's majority expressly declined to consider Trump's public statements calling for a Muslim ban; Sotomayor's dissent quoted those statements at length and compared the ruling to Korematsu v. United States.
