Pentagon restricts access to classified documents after their 'leakage' 

CBS writes about this.

According to U.S. officials, the number of people on government-wide distribution lists who receive classified updates has been culled significantly since Friday. Before the leak was revealed, about 1,000 people usually had access to these types of documents. 

"The Pentagon's internal review of the matter will be led by Milancy Harris, deputy under secretary of defense for intelligence and security. The review will probe the scope and scale of the leak and the impact on the U.S. and allies' national security, and examine how information flows and who has access to it," the journalists noted.

• On April 6, The New York Times reported on the leak of classified documents detailing US and NATO plans to build up the Ukrainian army before the planned counteroffensive. The Pentagon launched an investigation.

• Currently, the Pentagon is still assessing the extent of the leak, which is also related to Ukraine. Advisor to the President's Office Mykhailo Podolyak, in turn, noted that the documents did not contain information about the Ukrainian Armed Forces' counteroffensive.

• Some of these documents did not pass the authenticity test, and the White House called them fakes. And Associated Press journalists found out that the person who published the secret Pentagon documents on Discord might be a child.
