Who will leave Trump's Cabinet next?

Hegseth has the clearest mix of vulnerability and visibility among the listed contenders. The reporting points to a messy Pentagon environment, resignation churn, and repeated public criticism, which are exactly the kinds of conditions that can turn a Cabinet secretary into the next forced exit if the administration decides the controversy has become too expensive. In a Trump presidency, personnel decisions often hinge less on institutional process than on whether a figure becomes a sustained embarrassment, and Hegseth appears closer to that danger zone than most peers.

The main reason not to go much higher is that the evidence is still largely inferential. The strongest claims are framed by commentators and opinion writers rather than definitive reporting of an imminent firing, and the White House has publicly signaled that Trump still has confidence in him. That matters because Trump often tolerates internal dysfunction for a long time, especially when a secretary is aligned with his broader political message or when the alternative is admitting a personnel mistake.

Relative to the other contenders, Hegseth still grades out as the most likely next departure, but not decisively so. Brooke Rollins has comparable market support and could become vulnerable if policy or management problems surface, while Markwayne Mullin, Howard Lutnick, and Robert F. Kennedy Jr. all have their own pathways to trouble if they generate sustained political or operational blowback. My read is that the market is modestly underrating Hegseth’s proximity to the exit because the visible Pentagon chaos is a stronger near-term signal than the price suggests, but the market is also correctly discounting the fact that Trump’s public backing can keep a threatened secretary in place for much longer than headlines imply.
