WASHINGTON (AP) — The White House is vigorously defending President Donald Trump's immigration restrictions, as protests spread throughout the country. Some Republicans in Congress urged caution amid legal challenges to the order banning travelers from seven predominantly Muslim countries, though top congressional Republicans remain largely behind the new president.

That, despite widespread confusion and an apparent walk-back about how the order, which temporarily bars the citizens of seven majority Muslim nations from entering the U.S., would be applied to certain groups, like U.S. legal permanent residents.

Trump's order, which also suspends refugee admissions for 120 days and indefinitely bars the processing of refugees from Syria, has sparked widespread protests and denunciations from Democrats and a handful of Republicans.
