The high court said in two similar one-page orders that lower court rulings that partly blocked the latest ban should be put on hold while appeals courts in San Francisco and Richmond, Virginia weigh the cases. Both courts are due to hear arguments in those cases this week.
The Supreme Court said the ban will remain in effect regardless of what the appeals courts rule, at least until the justices ultimately decide whether to take up the issue on the merits, which they are highly likely to do. The court's order said the appeals courts should decide the cases "with appropriate dispatch."
