From the story here:
The high court on Wednesday blocked Watson’s order as it applies to refugees, but not the expanded list of relatives. The justices said the federal appeals court in San Francisco should now consider the appeal. It’s not clear how quickly that will happen.
In the meantime, though, up to 24,000 refugees who already have been assigned to a charity or religious organization in the U.S. will not be able to use that connection to get into the country.
