BOSTON -- Massachusetts Air National Guard member Jack Teixeira pleaded guilty on Monday to leaking highly classified military documents about the war in Ukraine and other national security secrets under a deal with prosecutors that calls for him to serve at least 11 years in prison.
Teixeira, of North Dighton, Mass., pleaded guilty to six counts of willful retention and transmission of national defense information under the Espionage Act nearly a year after he was arrested in the most consequential national security leak in years.
The 22-year-old admitted illegally collecting some of the nation's most sensitive secrets and sharing them with other users on Discord, a social media platform popular with people playing online games.
U.S. District Judge Indira Talwani scheduled sentencing for September in Boston's federal court and said she would decide then whether to formally accept the agreement, which calls for a prison sentence between 11 and nearly 17 years. Prosecutors said they plan to seek the high end of that range.
"Mr. Teixeira callously disregarded the national security of the United States and he betrayed his solemn oath to defend the country and the trust of the American people he swore to protect," Matt Olsen, assistant attorney general for national security, told reporters after the hearing.
The stunning security breach raised alarm over America's ability to protect its most closely guarded secrets and forced the Biden administration to scramble to try to contain diplomatic and military fallout. The leaks embarrassed the Pentagon, which tightened controls to safeguard classified information and disciplined members found to have intentionally failed to take required action about Teixeira's suspicious behavior.
Teixeira smiled at his father before being led out of the courtroom with his hands and legs shackled, wearing orange jail garb and black rosary beads around his neck. He stood flanked by defense attorneys through much of the hearing and occasionally leaned down to speak into the microphone to answer questions from the judge.
Michael Bachrach, an attorney for Teixeira, told reporters they will push for a sentence of 11 years. Bachrach described Teixeira as a "kid," adding that the defense will show at sentencing that his youth played a significant role in his conduct.
"He is significantly remorseful for his conduct. He has accepted full responsibility for his conduct," Bachrach said.
In an emailed statement, Teixeira's family said: "It is unfathomable to think your child would ever be involved in something so serious, but he has taken responsibility for his part in this, and here we are."
Teixeira, who was part of the 102nd Intelligence Wing at Otis Air National Guard Base in Massachusetts, worked as a cyber transport systems specialist, essentially an information technology specialist responsible for military communications networks. He remains in the Air National Guard in an unpaid status, an Air Force official said.
In exchange for Teixeira's guilty plea, prosecutors agreed not to charge him with further Espionage Act violations. As part of the deal, Teixeira must participate in a debrief with members of the intelligence community, the Defense Department and the Justice Department about the leaks.
