A member of the Massachusetts Air National Guard who leaked classified Pentagon information has been jailed for 15 years.
Jack Teixeira shared documents that contained information about the war in Ukraine on the messaging platform Discord.
The leak exposed information about troop movements in Ukraine, and the provision of supplies and equipment to Kyiv’s soldiers.
He began sharing the documents in 2022, Sky News’ US partner network NBC News reported, and had held top-secret security clearance since the year before.
Teixeira pleaded guilty earlier this year to six counts of wilful retention and transmission of national defence information following his arrest in the most consequential national security case in years.
Wearing an orange jumpsuit, he showed no visible reaction as he was sentenced by US district judge Indira Talwani.
Before being sentenced, he apologised for his actions, saying: “I wanted to say I’m sorry for all the harm that I brought and caused.”
He referenced the “maelstrom” he created and added: “I understand all the responsibility and consequences fall upon my shoulders alone and accept whatever that will bring.”
Afterwards, Teixeira, of North Dighton, Massachusetts, hugged one of his lawyers and looked toward his family and smiled, before being led away.

The security breach raised alarm over America’s ability to protect its most closely guarded secrets and left the Biden administration scrambling to try to contain the fallout.
The leaks were also embarrassing for the Pentagon which tightened controls and disciplined members who failed to take necessary action over the 22-year-old’s suspicious behaviour.

Assistant US attorney Jared Dolan said Teixeira’s sentencing would “be a cautionary tale for the men and women in the US military”.
Teixeira’s own lawyers said that while his actions were criminal, they were never intended to “harm the United States”.

“Instead, his intent was to educate his friends about world events to make certain they were not misled by misinformation,” the lawyers claimed.
Prosecutors in court said he tried to cover his tracks as they found a smashed tablet, laptop and Xbox in a rubbish bin at his house.
Teixeira, who was part of the 102nd Intelligence Wing at Otis Air National Guard Base in Massachusetts, worked as a cyber transport systems specialist – an information technology specialist responsible for military communications networks.
