'Something has to kick off': Trump said to be hitting 'major hurdles' to keeping promise

Donald Trump made a key campaign promise that's going to be difficult to keep, according to a report. "In private, his allies have been crafting strategies to do that, including directing the State Department to not issue passports to children with undocumented parents and tighten requirements for tourist visas to crack down on 'birth tourism,' according to two sources familiar with the planning," the outlet reported. "Multiple options are being kicked amongTrump allies to tighten the interpretation, keenly aware that any action would likely get legally challenged and eventually land before the Supreme Court." "A legal fight would be inevitable, but getting the Supreme Court to take up such a challenge is not a guarantee, and the high court will be less inclined to do so if there is no disagreement among the circuits about the meaning of birthright citizenship," according to the outlet. The CNN report also notes that, "Longstanding Supreme Court precedents are also a major hurdle for the incoming Trump administration."
