The Massachusetts Air National Guardsman accused of leaking highly classified military documents has been indicted on federal felony charges, the Justice Department said Thursday, according to The Associated Press.

Jack Teixeira faces six counts in the indictment of willful retention and transmission of national defense information.

Teixeira was taken into custody by the FBI at his home in North Dighton, Massachusetts in April, on charges of sharing highly classified military documents about Russia’s war in Ukraine and other top national security issues in a chat room on Discord, a social media platform that started as a hangout for gamers.

A judge last month ordered him to remain jailed as he awaits trial, saying that releasing Teixeira would pose a risk that he would attempt to flee the country or obstruct justice.

One of the leaked top-secret documents contained a short paragraph about Israel and alleged involvement by Mossad officials in the protests against the government’s judicial overhaul.

Another top-secret document that was leaked contained a US intelligence analysis of Israeli policy regarding military aid to Ukraine and stressed that US pressure could drive Israel to deliver more military assistance to Kyiv.
