BOSTON (AP) – Bills paid on an online social media platform and interviews with another user helped the FBI identify a Massachusetts Air National Guard member as the suspect in the leak of highly classified military documents, according to court records. classified.
The new details came to light after 21-year-old Jack Teixeira appeared in court to face charges under the Espionage Act for the unauthorized acquisition and retention of classified and national defense information.
A federal judge ordered that he be held until a detention hearing next week.
Jack Teixeira was arrested Thursday by heavily armed agents following a week-long criminal investigation into government whistleblowing, a breach that exposed to the world secret assessments of the war in Ukraine, the capabilities and geopolitical interests of other countries and other issues. of national security.
Investigators believe Jack Teixeira was the leader of a private online chat group on Discord, a social media platform popular with people who play online games. According to an FBI statement, payment records the FBI obtained from the Discord platform, which has said it is cooperating with the bureau, helped investigators identify Jack Teixeira.
According to a written statement filed in court, the FBI on Monday interviewed a person who had knowledge of Jack Teixeiras' online postings. That person, who was not identified in the affidavit, told the FBI that a username associated with suspect Teixeira began posting information that appeared to be classified as early as December.
The affidavit suggests that Jack Teixeira first printed out new copies of the documents but then took them home to photograph because he "was concerned that he might be found out doing the transcriptions of the text in the workplace".
That differs from what other posters have told The Associated Press and other media outlets, that the user they called "OG" started posting images of documents because he was unhappy that other users weren't taking him seriously.
The court filing also claims that Jack Teixeira was dictated to on April 6 — the day the New York Times first published an article about the leaked documents — searching for the word "leaked" in a classified system. The FBI says that suggested Teixeira was trying to find information on the leak investigation.
President Biden's administration has been scrambling to contain potential diplomatic and military fallout from the leaks since they were first announced last week, taking steps to reassure allies and assess the extent of the damage.
The classified documents - which have not been confirmed by US officials - range from information showing Ukraine's military positions to assessments of international support for Ukraine and other sensitive topics, including the circumstances under which Russian President Vladimir Putin might use nuclear weapons.
It was not immediately clear how Jack Teixeira would have gained access to the data, but a Defense Department official told The Associated Press on Thursday that as an information technology specialist in charge of military communications networks, the junior member of the Guard, there had been a higher level of security.
Defense Secretary Lloyd Austin, in a statement released after the arrest, said the Pentagon would conduct a review of its "intelligence approach, accountability and control procedures" to prevent such a leak from happening again.
