After the Ninth Circuit Court of Appeals upheld the preliminary injunction on the Trump Administration's "Travel Ban #1," President Trump issued a new Executive Order on March 6, 2017 that included a temporary 90-day ban on U.S. entries by citizens of Iran, Libya, Somalia, Sudan, Syria, and Yemen. This travel ban was challenged in the U.S. District Court of Maryland, which issued a nationwide preliminary injunction. On May 25, 2017, the Fourth Circuit Court of Appeals upheld the nationwide preliminary injunction on "Travel Ban #2" imposed by the Administration.

On June 1, 2017, the Administration filed an appeal (petition for a writ of certiorari) of the Fourth Circuit's decision on the preliminary injunction with the U.S. Supreme Court. Litigation on the core matter, apart from the preliminary injunction, will undoubtedly continue.For now, the preliminary injunction on "Travel Ban #2" remains in place.
