The U.S. Supreme Court is due to rule on Tuesday on whether to let President Donald Trump restrict birthright citizenship in the United States - one of the top priorities in his crackdown on immigration - in a case involving a right that had long been woven into the fabric of American society.
A lower court blocked Trump's executive order directing U.S. agencies not to recognize the citizenship of children born in the United States if neither parent is an American citizen or legal permanent resident, also called a "green card" holder.
