Federal courts have so far uniformly blocked President Donald Trump’s order seeking to end birthright citizenship for children born in the United States to someone in the country illegally.

The Supreme Court gave a skeptical hearing Thursday to a lawyer for President Trump who was appealing rulings that blocked his plan to deny citizenship to newborns whose parents were in this country illegally or temporarily.

Norman Wong, whose great-grandfather brought the landmark case that enshrined birthright citizenship, says the new fight over the issue is "for the soul of our country."
