Biden administration faces tough questions over Pentagon leak investigation.

Democratic Senator Kirsten Gillibrand has raised questions about the circumstances surrounding the leak of highly classified Pentagon documents by an airman with top-secret security clearance. The Biden administration has been scrambling to rectify damages after the airman posted documents online that revealed blunt details on the US intelligence assessment of the war in Ukraine as well as the extent of US eavesdropping on key allies. The Pentagon breach has left looming questions about national security implications, and Congress is vowing to investigate what happened and why the US intelligence community failed to discover its secrets were on a public internet forum for weeks.
