The Supreme Court has upheld a broad conception of birthright citizenship, rejecting President Donald Trump’s executive order declaring that children born to parents who are in the United States illegally or temporarily are not American citizens. The decision is in line with the longstanding judicial interpretation of the 14th Amendment and comes on the final day of a Supreme Court term that has centered on Trump’s expansive claims of presidential power — and largely ruled in his favor. In its other Tuesday rulings, the court upheld laws in roughly half the states that prohibit transgender girls and women from playing on their public school and college sport teams and struck down limits on party spending in federal elections.
