Rep. Jason Crow, a member of both the House Intelligence Committee and the House Armed Services Committee, recently told CBS News during an interview with "Face the Nation with Margaret Brennan" that Congress has not been given briefings about an ongoing investigation into a Pentagon leak. The probe is being led by Defense Secretary Pete Hegseth and is part of a broader effort, according to Crow, to create fear and control the flow of information from the Pentagon. Crow emphasized that he and other lawmakers have not been provided with any details about the investigation into how highly classified information about the U.S. stockpiles of advanced weapons was leaked to the media. Instead, they have learned about the probe through public reports. Officials familiar with the investigation told CBS News that some of the highest-ranking members of the U.S. military were required to take polygraph tests after President Trump expressed frustration over the leaks. While polygraph tests are not uncommon for top military personnel, conducting them on such a large scale is rare. Officials clarified that not all senior military leaders were subjected to the tests, and no one failed the exams. The tests were designed to identify who might have leaked classified information about U.S. munitions stockpiles to the media. Crow also pointed out that since taking on the role of Defense Secretary at the start of the current Trump administration, Hegseth has removed more than 80 generals and admirals from the Department of Defense—representing the top 10% of the military's leadership. Additionally, Crow noted that the number of women eligible for promotions in the military has reached a 25-year low under Hegseth’s leadership. He suggested that the decision to withhold information about the leak investigation from Congress is part of a broader trend within the Trump administration to limit transparency, including with members of Congress. The investigation was initiated after media reports revealed a rapid depletion of some of the country's most advanced weapons systems several weeks into the Iran war, sparking concerns about the military's preparedness for future conflicts. When asked about the current state of these reported shortages, Crow said, "They don't want people to know. This is exactly the point. They don't want people to know what's actually happening."
