Investigations launched into Ukraine document leak and US intelligence on allies and foes.

The Justice Department and Pentagon are investigating how classified U.S. documents about the war in Ukraine ended up on social media platforms. The documents appear to be briefing slides focused on Ukraine, with maps and charts pertaining to their troops and weapons. Former Justice Department "leak czar" Brandon Van Grack says national security damage has certainly been done, and the priority now is identifying who leaked the documents and ensuring there are no further leaks. The investigation is ongoing, and it's not yet clear what kind of impact the leaked material could have on the trajectory of the war.
