(CNSNews.com) – The White House said Thursday that the Defense Department (DoD) has taken steps to “further restrict access to sensitive information” in the wake of the leaked DoD classified documents.

“I’m sure you’ve seen the Washington Post reporting about the alleged leaker.  What does it say about the security of our nation’s top secrets if they’re able to be posted online like this, in a chat room, apparently for years, undetected?” ABC Senior White House Correspondent Mary Bruce asked during a press gaggle in Belfast, Northern Ireland.

“So I’ll first say this: As you know, there’s an ongoing investigation that’s being led by the Department of Justice. That’s something that the Department of Defense quickly asked for once they learned about these documents, and I will also say the Department of Defense has said they have taken steps to further restrict access to sensitive information,” White House Press Secretary Karine Jean-Pierre said.

“Look, we are — we are certainly reviewing the national security implications of the disclosure, and I can add that, you know, to mitigate the impact the release of these documents have on our U.S. — U.S. national security and also on our allies and partners as well, and so this is something that we are taking very seriously,” she said.

“There is an ongoing investigation. DOD has taken steps to restrict access to these documents, and I definitely don’t want to get ahead of what’s currently happening,” the press secretary said. 

“And just one more. Does the president feel the Pentagon needs to reassess how it monitors social media, these kinds of platforms, or maybe even the activities of its own employees on these platforms?” Bruce asked.

“So — and I think we’ve mentioned this before — you know, this is something for the intelligence community; they have conversations, clearly, at that — at that level. Don’t want to get ahead of that, and, you know, just want to be very careful here,” Jean-Pierre said.

“We do believe that social media companies have a responsibility to their users and to the country to manage the private sector infrastructure that they create and now operate,” the press secretary said.  

“So we do believe that they have a responsibility, but I’m just not going to — and we urge — right? — we normally urge companies to avoid facilitating those circulation of material determina- — detrimental to public safety and national security, but any further conversations or how changes are going to happen as it relates to that, I’m certainly not going to speak to that here,” she said.
