What You Need To Know

  • President Joe Biden on Thursday for the first time commented publicly about the release of Pentagon documents that appear to detail U.S. and NATO aid to Ukraine and U.S. intelligence assessments regarding U.S. allies 

  • Biden said that while he was concerned that sensitive government documents had been leaked, “there's nothing contemporaneous that I'm aware of that is of great consequence"

  • Biden noted that a “full-blown” investigation was underway by the intelligence community and the Justice Department on who leaked the information

  • Some of the documents may have been altered or used as part of a misinformation campaign, U.S. officials said

It was the first time Biden has commented publicly about the release of Pentagon documents that were posted on several social media sites. They appear to detail U.S. and NATO aid to Ukraine and U.S. intelligence assessments regarding U.S. allies that could strain ties with those nations. The Justice Department has opened an investigation.

“I’m concerned that it happened, but there’s nothing contemporaneous that I’m aware of that is of great consequence," said Biden, who is in Dublin visiting with Irish leaders Thursday.

Biden noted that a “full-blown” investigation was underway by the intelligence community and the Justice Department on who leaked the information. “We're getting close," he said. "But I don't have an answer.”

There are no clear answers on how many documents were leaked. The Associated Press has viewed approximately 50 documents; some estimates put the total number in the hundreds.

Some of the documents may have been altered or used as part of a misinformation campaign, U.S. officials said. National Security Council spokesperson John Kirby on Monday urged caution, “since we know at least in some cases that information was doctored.”

No one knows for sure where they came from, not even the Pentagon chief.

“They were somewhere in the web, and where exactly, and who had access at that point, we don’t know. We simply don’t know,” Defense Secretary Lloyd Austin said at a news conference Tuesday. “We will continue to investigate and turn over every rock until we find the source of this and the extent of it.”

It’s possible, though, that the leak may have started on a site called Discord.

Discord is a social media platform popular with people playing online games. The Discord site hosts real-time voice, video and text chats for groups and describes itself as a place “where you can belong to a school club, a gaming group, or a worldwide art community.”

On Thursday, White House press secretary Karine Jean-Pierre urged social media companies to “avoid facilitating the circulation of material detrimental to public safety and national security.”

“We do believe that social media companies have a responsibility to their users and the country to manage the private sector infrastructure that they create and then operate," she said.
