The U.S. Supreme Court Monday rejected a request by Elon Musk's X Corp., the social media company formerly called Twitter, to consider whether it can publicly disclose how often federal law enforcement seeks information about users for national security investigations.

The justices declined to hear X's appeal of a lower court's ruling holding that the FBI's restrictions on what the company could say publicly about the investigations did not violate its free speech rights under the U.S. Constitution's First Amendment.
