Jack Teixeira: Suspect in Pentagon documents leak named

The suspect in the leaking of highly sensitive US defence and intelligence documents is named as Jack Teixeira, US officials tell CBS News.

The New York Times earlier reported that the leader of an online gaming chat group where the files leaked in recent months had the same name.

The paper said he is a 21-year-old member of the intelligence wing of the Massachusetts Air National Guard.

Its report did not identify Mr Teixeira as the alleged leaker.

The New York Times cited interviews with other members of the online group, one of whom said he had known the person who leaked the files for at least three years.

At least 50 but perhaps more than 100 secret documents were posted on Discord - a social media platform popular with gamers.

The documents contain a range of intelligence assessments about the war in Ukraine, but also sensitive intelligence about countries around the world, including US allies.

He described the leaker as a young, charismatic gun enthusiast in his early to mid-20s who works at an unnamed military base.

The Post reported that the man was the leader of a Discord chat room including roughly two dozen members who swapped "memes, offensive jokes and idle chitchat" and prayed and watched movies together.

The members included people from Russia and Ukraine and a number of other countries in Europe, Asia and South America, the paper reported.

At first the leaks were kept inside the small chat room, but in early March members began posting them on other Discord servers, including ones dedicated to the game Minecraft and a Filipino YouTuber.

From there they were posted on the fringe message board 4chan and on the Telegram chat app, particularly on pro-Russia channels. In some cases they were altered to increase Ukrainian casualty counts.

Earlier, while on a trip to Ireland, US President Joe Biden said investigators were close to finding the person who leaked the documents.

"There's a full blown investigation going on, as you know, with the intelligence community and the Justice Department, and they're getting close," Mr Biden told reporters.

The FBI has not identified a suspect in the leak.
