National guardsman suspected to be behind US military document leaks arrested

Pentagon press secretary Air Force Brigadier General Pat Ryder, addressing reporters on Thursday, said the leaks were being taken “very seriously”.

Asked if the US would make changes to its security policies, he said steps had already been taken to review distribution lists.

“We do have stringent guidelines in place for safeguarding classified and sensitive information,” he added.

“This was a deliberate criminal act, a violation of these guidelines.”

However, he refused to comment on the identity of the suspect.

“Given this is an ongoing investigation, I’m not going to be able to talk about the investigation or any potential Department of Justice action,” he told reporters.

‘Nothing contemporaneous’

It comes after US President Joe Biden said he was “concerned” about the widespread leaks, that have rocked The Pentagon.

While their accuracy has been questioned, the leaked documents appear to reveal potential vulnerabilities in Ukraine’s defences, as well as the numbers of UK special forces allegedly active in the country.

Mr Biden said that while he was “concerned” sensitive information had been leaked, “there’s nothing contemporaneous that I’m aware of that is of great consequence”.

He noted there was a “full-blown” investigation by the intelligence community and the US Justice Department. “We’re getting close,” he said, on the probe into what happened.

“But I don’t have an answer.”

Known as “OG” in the chatroom, the suspect behind the leaks allegedly claimed to spend parts of his day inside a secure facility where phones were banned, according to a story published by the Washington Post.

Teixeira is believed to have posted for years about guns, games and his favourite memes – and, according to some others chatting with him, closely guarded US secrets.

He initially typed up versions of highly secret documents and posted them for the group of about 25 active members from various countries to read, but later switched to posting slews of photos of the documents themselves.

What do the highly classified documents say?

As well as sharing state secrets in the group, named “Thug Shaker Central”, OG would also forecast major events before they became headline news, according to another member of the chat interviewed by the Post.

However, friends told the Post that OG was “not interested in helping any foreign agency” and that he was a “young charismatic man” who was attempting to impress friends.

How were the documents leaked?

The scale of the scandal has been compared to the Edward Snowden leaks in 2013.

Various theories have emerged about how the highly classified documents came to be made public, including a potential Russian hack.

But defence and security expert Professor Michael Clarke said that the leak could be an issue with the number of people who have access to classified documents in the US.

Though the US operates a “need to know” policy, it also has a “dare to share” philosophy which means an estimated 1.3 million people have access to secret and top secret documents.

Speaking to the Sky News Daily Podcast, he said: “In the American system, it is ‘dare to share’ which is to get everybody on board with a common picture of what we’re talking about and, of course, it’s based on the idea that proper Americans are patriotic enough not to leak material.

“But if 1.3 million people have got access to some form of secret material then even a small proportion – 0.1% of those people – if they are geeks who want to be a bigshot amongst their friends, as this person probably did…then some people like that will emerge from the system.”

What do the documents show?

As more and more of the information contained in the documents is reported, the reach of American intelligence agencies is increasingly under the spotlight.

According to the New York Times, the documents also illuminate the depth of infighting inside the Russian government.

They paint a picture of feuding behind the walls of the Kremlin over the number of casualties in the Ukrainewar.

Officials in several countries have denied or rejected allegations from the leaked records.

Kremlin spokesperson Dmitry Peskov told Sky News: “Like everyone else, we don’t know the degree of authenticity of these documents.

“But even if we disengage from them, long before these documents appeared, we had and still have information that many instructors, including the ones from Britain, and fighters are taking part in the military actions.”
