Defense Secretary Pete Hegseth has fired or ousted multiple high-level military commanders including Gen. Chris Donahue, triggering rare bipartisan concern from both Republican and Democratic lawmakers. The firings have prompted congressional discussion of new guardrails to limit Pentagon personnel decisions, with Sen. Tim Kaine indicating the effort could attract cross-party support. Several GOP lawmakers have publicly criticized Hegseth for undermining military stability and creating a climate of fear at the Pentagon.
