Today’s case stems from an executive order President Donald Trump signed in January 2025 on his first day back at the White House.
It sought to end automatic citizenship for children born to parents who were in the US temporarily or illegally. The Trump administration argues the order will clamp down on illegal immigration.
Hours after Trump signed it, various lawsuits were launched by Democratic-run states and cities, civil rights groups and individuals.
Three federal judges tried to block the order from taking effect by issuing nationwide injunctions.
After the Supreme Court ruled against the injunctions, the case came back as a class action lawsuit – which is where multiple similar claims are brought together into a single suit.
The court first heard oral argument on this case – called Trump v Barbara – in April.
