DOJ investigates source of leaked Pentagon documents revealing Ukraine war intelligence.

The US government is investigating a leak of highly classified Pentagon documents, with the Pentagon examining how the leak impacts national security and the Justice Department launching a criminal investigation into who may have been behind the breach. The investigation will chiefly examine whether any sources and methods have been compromised since the documents, many of which are marked Top Secret, were posted on a social media platform earlier this year. The Pentagon effort is not focused on the source of the leak, but the Defense Department will be examining how it distributes highly classified information and whether it needs to change who receives it on a daily basis.
