On Thursday, the Supreme Court will take up a case that could decide how quickly President Donald Trump can implement his second term agenda as it hears arguments about nationwide injunctions that allow a single judge to block a policy for the entire country.

The Supreme Court will hear arguments tomorrow about birthright citizenship. How we got here: Trump tried to ban giving U.S. citizenship to children born to foreign visitors and undocumented immigrants. After judges stepped in, he appealed to the high court.

A judge arrested by the Trump administration is now citing the Supreme Court's immunity ruling in her defense.
