Oral Argument Transcript at 11-12:
JUSTICE SOTOMAYOR: No, we don't, because the argument here is that the president is violating an established -- not just one but, by my count, four established Supreme Court precedents. We have the Wong Ark case, where we said fealty to a foreign sovereign doesn't defeat your entitlement -- your parents' fealty to a foreign sovereign doesn't defeat your entitlement to citizenship as a child. We have another case where we said that even if your parents are here illegally, if you're born here, you're a citizen. We have yet another case that says, even if your parents came here and were stopped at the border and -- but you were born in our territory, you're still a citizen. And we have another case that says, even if your parents secured citizenship illegally, you're still a citizen. So, as far as I see it, this order violates four Supreme Court precedents.
