The Supreme Court is reviewing nationwide injunctions that blocked Trump's executive order targeting birthright citizenship.

Justice Alito pointed out that multiple states have also sued over the birthright citizenship order and won broader victories. The Trump administration is also arguing that states shouldn’t have been able to do that, but Sauer sticks to his point about the nationwide injunctions, saying they yield “all these sort of pathologies.”

The Supreme Court on Thursday seemed open to lifting a series of nationwide orders blocking President Donald Trump from enforcing his birthright citizenship policy, even as several of the justices wrestled with the practical implications of allowing the government to deny citizenship to people born in the US.
