Jack Douglas Teixeira, a 21-year-old U.S. Air Force National Guard airman, was arrested and charged with unlawfully copying and transmitting classified military intelligence documents to the internet. 

Teixeira appeared before a federal judge in Boston, Massachusetts, where he faces serious charges under the Espionage Act, with each offense carrying up to 10 years in prison. U.S. President Biden has directed the military and intelligence community to further secure and limit the distribution of sensitive information following the leak.

The FBI's investigation into the disclosure of the classified documents, which exposed secret assessments on the war in Ukraine, the capabilities and geopolitical interests of other nations, and other national security issues, was aided by billing records and interviews with social media comrades. Investigators believe Teixeira was the leader of an online private chat group on Discord, a social media platform popular with gamers.

The group, known as Thug Shaker Central, had about two dozen members who discussed their favorite types of guns, shared memes, jokes, and held conversations about wars, including Russia's invasion of Ukraine.

A Discord user familiar with Teixeira’s online posts provided the FBI with basic identifying information, including that he called himself “Jack,” claimed to be part of the Air National Guard, and appeared to live in Massachusetts. The FBI obtained billing records from Discord, which was cooperating with the bureau, to help lead them to Teixeira.

Teixeira allegedly switched from typing out documents in his possession to taking them home and photographing them because he was concerned about being discovered making transcriptions in the workplace. According to some users, Teixeira started posting images of documents as he was annoyed that other users weren't taking him seriously. 

On April 6, the day The New York Times first published a story about the breach of documents, Teixeira was detected searching for the word “leak” in a classified system. The FBI believes he was attempting to find information about the investigation into the person responsible for the leaks.

Although the Justice Department has not alleged a particular motive, accounts from the online private chat group where the documents were disclosed depict Teixeira as motivated more by bravado than ideology. His court appearance was brief, and he did not enter a plea. A detention hearing has been scheduled for next week. 

Meanwhile, the Biden administration is working to contain the potential diplomatic and military fallout from the leaks, reassuring allies and assessing the scope of the damage.
