Airman charged as US vows to send message over documents leak

A young national guardsman was charged Friday with orchestrating the most damaging leak of US classified documents for a decade, as the government signaled it intends to make an example of the 21-year-old.

Jack Teixeira was arrested Thursday following a week-long probe into the leak of documents – which unveiled US concern over Ukraine's ability to fend off the Russian invasion, and showed Washington has spied on allies Israel and South Korea.

It is the biggest such breach since the 2013 dump of National Security Agency documents by Edward Snowden and raises tough questions over the access of junior staffer Teixeira to high-level secrets.

Teixeira, who wore a beige jumpsuit and appeared glum at his first court appearance in Boston, was charged with the "unauthorised retention and transmission of national defense information."

He is also accused of the "unauthorised removal and retention of classified documents or material." The counts carry maximum prison sentences of 10 years and five years, respectively.

At one point during the short hearing, his father shouted out, "We love you Jack," to which Teixeira responded: "Love you too, Dad."

He was not required to enter a plea and was held pending a detention hearing set for next Wednesday.

US Attorney-General Merrick Garland said there were "very serious penalties" associated with the crimes.

"People who sign agreements to be able to receive classified documents acknowledge the importance to the national security of not disclosing those documents, and we intend to send that message how important it is to our national security," Garland added.

US President Joe Biden said Friday that he had ordered the military and intelligence community to tighten security around sensitive information after the breach.

Teixeira is suspected of posting the documents, some dated as recently as early March, to a private chat group on the social media platform Discord.

The New York Times reported that Teixeira was the leader of the group called Thug Shaker Central and reportedly posted the documents under the nickname "OG."

He first wrote down the contents of classified documents to share with the group, but later began taking photos, telling other members not to share them, according to a court affidavit by an FBI agent released Friday.

Some of the documents later appeared on other sites, including Twitter, 4Chan and Telegram.

Investigators have not yet suggested what Teixeira's motive was.

He enlisted with the US Air Force National Guard in September 2019 and was an IT and communications specialist who reached the rank of airman first class – the third-lowest for enlisted air force personnel.

Friends of Teixeira described him to The Washington Post as a devout Catholic and libertarian who is interested in guns.

The newspaper reported that his father spent 34 years in the same military unit as his son, while Teixeira's mother worked for non-profit organisations that support veterans.

Teixeira's dramatic arrest at his home in the southern Massachusetts town of Dighton was broadcast live on US TV networks Thursday.

Helicopter footage of the operation showed the suspect dressed in red shorts and a T-shirt with his hands behind his head, backing slowly toward rifle-armed, camouflage-clad law enforcement personnel who took him into custody.

Friday's court affidavit said that Teixeira had possessed top secret security clearance since 2021 and was privy to further information that not everyone with a regular top secret clearance needs to know.

US Defense Secretary Lloyd Austin has said he is ordering a "review of our intelligence access, accountability and control procedures within the (Defense) Department to inform our efforts to prevent this kind of incident from happening again."
