Supreme Court Justice Samuel Alito was treated for dehydration at a hospital after a previously undisclosed March 20 incident in Philadelphia, sources told Fox News. 

He was not admitted and returned home the same night without complications.

Alito, 76, attended a Federalist Society dinner that evening and reported feeling lightheaded, prompting his security detail to recommend a precautionary hospital visit. Sources said the justice has had no issues since.
