The US president issued an executive order in 2025 that seeks to undo constitutional right to birthright citizenship

The US supreme court on Wednesday appeared poised to protect birthright citizenship, the longstanding policy that babies born in the US are American citizens, in what would be a blow to a key immigration policy for Donald Trump.

The court heard oral arguments with Trump himself in attendance inside the courtroom’s public gallery. A majority of justices asked questions indicating skepticism about the government’s attempt to overturn birthright citizenship. But while some expected the case to be a clearcut win for those challengingthe government, it is unclear how many justices might side with Trump. A decision is expected this summer.

If birthright citizenship is overturned, hundreds of thousands of children born annually would be blocked from US citizenship.
