FBI says it's investigating unauthorized release of documents on Israel's possible attack plans

The FBI says it's investigating the unauthorized release of classified documents on Israel’s preparation for a potential retaliatory attack on Iran. White House national security spokesman John Kirby said Monday that the Biden administration still wasn't certain if the classified information was leaked or hacked but that officials don’t have any indication at this point of “additional documents like this finding their way into the public domain.” The Associated Press reported on Saturday evening that U.S. officials were investigating the release. The FBI confirmed for the first time that it was investigating and “working closely with our partners in the Department of Defense and Intelligence Community.”
