Even as President Donald Trump insisted “it’s not really an FBI thing,” the reality is that the FBI and Justice Department for decades have been responsible for enforcing Espionage Act statutes governing the mishandling — whether intentional or negligent — of national defense information like the kind shared on Signal, a publicly available app that provides encrypted communications but is not approved for classified information.

The Justice Department has broad discretion to open an investigation, though Attorney General Pam Bondi, who introduced Trump at a Justice Department event this month, signaled at an unrelated news conference on Thursday that she was disinclined to do so. She repeated Trump administration talking points that the highly sensitive information in the chat was not classified, though current and former U.S. officials have said the posting of the exact launch times of aircraft and times that bombs would be released before those pilots were even in the air would have been classified.

Bondi signals probe into Signal chat is unlikely, despite a long history of similar inquiries

FBI Director Kash Patel may not have been part of a Signal chat in which other Trump administration national security officials discussed detailed attack plans.
