US National Guardsman Jack Teixeira pleads guilty to leaking top-secret Pentagon documents
Before his arrest, Teixeira had been an airman 1st class at Otis Air National Guard Base on Cape Cod in Massachusetts, where he worked as a cyber defence operations journeyman, or information technology support specialist.
He did so even though his superiors admonished him twice in September and October 2022 about his handling of classified information, according to internal Air National Guard records filed in court.

In December, the US Air Force announced it had moved to discipline 15 staff over the leak and relieved Colonel Sean Riley of the command of the unit to which Teixeira belonged.
It did so after an Air Force inspector general report on the incident found that some members of Teixeira’s unit and leadership “had information about as many as four separate instances of his questionable activity”.
A smaller number of people had a more complete picture of his intelligence-seeking behaviour and “intentionally failed to report the full details of these security concerns/incidents”, the report said.
The Air Force following the leaks said it implemented several reforms to improve procedures related to access to classified information.
