A third senior Pentagon staffer has been placed on leave amid a widening investigation into national security leaks. The Department of Defense is now using polygraphs to identify the source.
Key Facts:
- Colin Carroll, chief of staff to Deputy Secretary Stephen Feinberg, was placed on leave Wednesday.
- Two other officials, Dan Caldwell and Darin Selnick, were also suspended earlier this week.
- The investigation focuses on recent leaks involving the Panama Canal, Elon Musk’s Pentagon visit, and military deployment to the Red Sea.
- The Department of Defense will use polygraphs to identify the Pentagon leaker.
- Any confirmed leaker may face criminal prosecution, according to an internal memo.
Rest of the Story: Details Behind the Pentagon Leaker Suspensions
Three top officials from the Pentagon have now been sidelined in a fast-moving internal investigation into media leaks of national security information.
Colin Carroll, who served as chief of staff to Deputy Secretary Stephen Feinberg, was escorted from the building just a day after two other high-ranking officials—Dan Caldwell and Darin Selnick—were also placed on administrative leave.
The Department of Defense has not publicly disclosed the exact nature of the alleged leaks.
However, a source told Politico they involve sensitive issues such as a second aircraft carrier heading to the Red Sea, plans related to the Panama Canal, and Elon Musk’s controversial Pentagon visit.
This leak crackdown comes after a New York Times report claimed Musk might be briefed on classified war plans concerning China, a claim that former President Trump strongly denied.
“I would never show those plans to anybody,” Trump said.
The rot is so deep.

Commentary: Why National Security Leaks Must Be Met With Consequences
The Pentagon is not just a workplace—it is the nerve center of America’s military operations.
When classified plans involving troop deployments or strategic infrastructure like the Panama Canal are leaked, national security is at stake.
These are not casual office rumors.
They can put American lives in danger.
Leaks of this nature demand a swift and serious response.
Administrative leave should be the starting point, not the end.
If these men—trusted with the nation’s secrets—are found guilty of compromising them, they should not only be fired, but prosecuted to the fullest extent of the law.
Polygraphs may seem old-school, but in this case, they’re essential.
The Department of Defense has a duty to ensure that those who leak sensitive information are identified and removed.
Other agencies like the DOJ and DHS have already implemented similar tools.
The idea that anyone—whether aligned with a political movement, private industry, or even a public figure like Elon Musk—might be briefed on classified war strategies is deeply concerning.
It doesn’t just raise legal issues; it strikes at the heart of civilian trust in the military.
It’s also a question of precedent.
If high-ranking staffers leak and face no consequences, the floodgates are open.
That sends a dangerous message to both allies and adversaries: the U.S. can’t keep its secrets safe.
Whether these three individuals are guilty or not, the Pentagon must take a strong stance.
This is about more than three men—it’s about national integrity, discipline, and the rule of law in defense operations.
The Bottom Line: Pentagon Leaker Investigation
The Pentagon’s internal security is under intense scrutiny following the suspension of three high-level officials.
The Department is taking strong measures, including the use of polygraphs and potential prosecution, to find the source of the leaks.
This growing scandal raises urgent questions about who can be trusted with America’s military secrets—and how the government will respond when that trust is broken.
