The US government is investigating a major leak of classified Pentagon documents that were posted on social media sites last month. The documents include details about US intelligence operations on allies and adversaries, as well as intelligence on the war in Ukraine. The leak has raised concerns about the compromise of sensitive sources and foreign relationships. The Justice Department is investigating the matter, but little is known about who may have been responsible for the leak.
