Prosecutors will urge a U.S. judge to sentence Massachusetts Air National Guardsman Jack Teixeira to nearly 17 years in prison for leaking highly classified military documents, including records related to Russia's war in Ukraine. Teixeira pleaded guilty to six counts of willful retention and transmission of classified information. He faces separate military charges for obstructing justice and failing to obey orders. Defense team argues for an 11-year term, citing Teixeira's autism and intent to educate friends.
