(AP) — The Supreme Court is letting the Trump administration mostly enforce its 90-day ban on travelers from six mostly Muslim countries, overturning lower court orders that blocked it.

The action Monday is a victory for President Donald Trump in the biggest legal controversy of his young presidency.

The court did leave one category of foreigners protected, those “with a credible claim of a bona fide relationship with a person or entity in the United States,” the court said in an unsigned opinion. The justices will hear arguments in the case in October.
