Republican senators are expressing growing concerns about Defense Secretary Pete Hegseth’s leadership as the war with Iran continues without a clear resolution.

Some GOP lawmakers say the Pentagon failed to anticipate prolonged disruptions in the Strait of Hormuz, rising costs, and attacks by Iran-backed groups on U.S. allies and shipping routes.

Critics have also questioned the removal of senior military leaders and whether changes at the Pentagon have weakened strategic planning.

While some Republicans want a stronger military response to force Iran into concessions, others are frustrated by the conflict’s length, expenses, and lack of a clear endgame, The Hill has reported.

Support for additional war funding is uncertain as lawmakers demand more transparency on costs and the administration’s strategy.
