John Kirby says Biden administration unsure if leak or hack led to secret documents appearing online on Telegram

The FBI has launched an investigation into the unauthorized release of classified documents describing Israel’s preparation for a potential retaliatory attack on Iran.

The White House national security spokesperson, John Kirby, said on Monday that the Biden administration was still not certain if the classified information was leaked or hacked but that officials did not have any indication at this point of “additional documents like this finding their way into the public domain”.
