Most Americans support the rule that anyone born in the US is a US citizen, and a majority of supreme court justices are skeptical of Trump’s efforts to restrict it
The US president himself was in the room – the first sitting president to attend oral arguments at the court – coming face to face with justices that he has long berated and pressured to fall in line with his agenda. His attendance was a striking signal of just how significant this case is.
The egalitarian, universal rule that anyone born in the US is a US citizen was enshrined in the 14th amendment of the US constitution in 1868, and was affirmed by the supreme court 128 years ago. A ruling in favor of the Trump administration would cataclysmically redefine what it means to be an American.
In practical terms, it would mean that an estimated 250,000 babies born in the United States each year would be stripped of their citizenship. Some would be stateless. Legal experts warn that this outcome could pave the way for casting off citizenship from millions of people who already have it.
