(Reuters) – The Air National Guardsman accused of leaking highly classified U.S. military documents pleaded not guilty on Wednesday to six federal charges, CNN reported.
Jack Douglas Teixeira, 21, appeared in federal court in Worcester, Massachusetts, for arraignment following his arrest in April for disclosing US documents related to the war in Ukraine and numerous other sensitive issues.
Teixeira was held in federal prison in Plymouth County, south of Boston, pending trial. No trial date has been set.
Prosecutors say Teixeira leaked classified documents to a group of gamers on the Discord messaging app. The leak is considered the most serious breach of US national security as more than 700,000 diplomatic documents, videos and cables appeared on the WikiLeaks website in 2010.
The leaked documents contained highly classified information on allies and adversaries, with details ranging from Ukraine’s air defenses to Israel’s Mossad spy agency. President Joe Biden has ordered an investigation into why the alleged leaker had access to the sensitive information.
