President Joe Biden on Friday announced new actions that restrict access to classified materials in the wake of an embarrassing leak of apparent classified U.S. military intelligence that ended up spreading widely on social media.
The suspected leaker, a 21-year-old member of the Massachusetts Air National Guard named Jack Teixeira, was on Thursday arrested and charged in federal court on two counts, including unauthorized retention and transmission of national defense information charges.
“I commend the rapid action taken by law enforcement to investigate and respond to the recent dissemination of classified U.S. government documents,” Biden said in a statement.
“While we are still determining the validity of those documents, I have directed our military and intelligence community to take steps to further secure and limit distribution of sensitive information, and our national security team is closely coordinating with our partners and allies,” the president added.
Teixeira was an IT specialist responsible for military communications networks, which allowed him to get a higher level security clearance.
The leaked documents include maps and details about deliveries of weapons, with some bearing markings classifying them as “Secret” and “Top Secret.” Some showed what looks like locations for front-line Russian and Ukrainian military units and artillery guns.
Former Defense Secretary Mark Esper said in an appearance on Fox News on Friday that he’s baffled as to why someone like Teixeira would have had access to the sensitive materials.
“I don’t understand why a 21-year-old national guardsmen had access to some of the most highly kept secrets in the United States, and in particular, finished products from the Joint Staff or finished products from the CIA operation center,” Esper said. “I just don’t know why he would have access to those.”
Asked about reports that Teixeira worked in IT and needed clearance to work on computer networks and equipment, Esper said that his access should have been more limited and that information carried on military communication systems should have been ring-fenced.
“There’s not a need for him to have access to the information on that system, let alone finished products from the Joint Staff and CIA,” Esper replied, adding that an investigation into the leak shows that the Pentagon has a problem “not just over classification, but in this case, over distribution.”
“There’s too many people that have access to this information. It should really only be for the highest levels of our government,” Esper said. “And we need to get that under control.”
“It’s not just embarrassing, but it’s damaging,” Esper said, noting that the leak hurt Ukraine’s ability to mount an effective counter-offensive against Russian forces while burning U.S. access to Russian military and intelligence systems.
The leak may also have exposed sources and techniques of collecting intelligence on Chinese operations, he added.
Besides Biden announcing action to limit access to classified materials, Defense Secretary Lloyd Austin has vowed to take “any additional measures necessary” to safeguard against national security leaks and has ordered a review of intelligence access.
Austin said during a press conference on Thursday that he’s “directing the Under Secretary of Defense for Intelligence and Security to conduct a review of our intelligence access, accountability, and control procedures within the Department to inform our efforts to prevent this kind of incident from happening again.”
He said the Department of Defense, in close partnership with the Intelligence Community and its interagency partners, “will continue to review the national security implications of this unauthorized disclosure.”
Austin also stressed that “every U.S. service member, DoD civilian, and contractor with access to classified information has a solemn legal and moral obligation to safeguard it and to report any suspicious activity or behavior.”
Teixeira, a junior airman with the Air National Guard’s 102nd Intelligence Wing, worked as a cyber transport systems journeyman, meaning he was an IT specialist responsible for military communications networks, including their cabling and hubs.
According to defense officials, Teixeira would have had a higher level of security clearance in that role, given that he was tasked with accessing and ensuring the network was protected, although officials have yet to confirm if he did.
Officials believe Teixeira leaked the Pentagon documents earlier this year across platforms such as Discord, an instant messaging social platform popular with gamers.
Some of the documents were also posted to the Telegram app and 4chan.
Teixeira was arrested on Thursday at a residence in North Dighton, Massachusetts.
“Since late last week the FBI has aggressively pursued investigative leads and today’s arrest exemplifies our continued commitment to identifying, pursuing, and holding accountable those who betray our country’s trust and put our national security at risk,” the agency said in a statement.
Attorney General Merrick Garland said the probe into Teixeira centers on the unauthorized removal, retention, and transmission of classified national defense information.
