Analyzing the Pentagon Leak: FBI Investigation and National Security Risks

The FBI is leading an investigation into the leak of sensitive and secret defense and intelligence documents, which were shared on social media. The Pentagon is reducing the number of people who have access to classified information. The leaked documents appear to have been physically stolen, and the Pentagon's internal review will probe the scope and scale of the leak and the impact on national security. Former officials familiar with leak investigations predicted that identifying the source could happen quickly because "the universe of possibilities is relatively small."
