The FBI is investigating the leak of classified documents that detailed Israeli preparations to retaliate against Iran, as officials seek to clamp down on yet another embarrassing disclosure of US intelligence secrets.

U.S. officials are investigating an apparent leak of two “top secret” documents about Israel. The documents appear to outline American spy agencies’ intelligence on possible Israeli preparations for a retaliatory attack on Iran.

Shelley Moore Capito told NewsNation the U.S. needs to find out who did this. “To think that there’s this huge breach of trust, which appears to be, is just unconscionable on our part,” Moore Capito said.
