The president's contention that birthright citizenship is unconstitutional is considered a fringe view because the Supreme Court ruled to the contrary 127 years ago.

The Trump administration is pushing for the the U.S. Supreme Court to allow some restrictions on birthright citizenship even as legal battles continue over President Donald Trump's orders to end what has long been seen as a constitutional promise.

The order, if approved, would deny citizenship to those born after Feb. 19 whose parents are in the country illegally.
