Why are US Republicans losing faith in War Secretary Pete Hegseth?

The Republican Party’s confidence in United States Defense Secretary Pete Hegseth appears to be waning, amid growing frustrations over the war with Iran dragging on with no end in sight.

“I don’t have any confidence in him anymore. I think he’s all over the place,” Senator Thom Tillis said of Hegseth in an interview with US newspaper The Hill last week. “I think he’s got a massive insecurity complex, he has a lack of experience in large organisations, he micromanages too much.”

Tillis spoke of a growing crisis of confidence in Hegseth’s leadership within the Senate, as the US and Iran appear no closer to a lasting peace deal despite the soaring costs of the war that the US and Israel launched on Iran on February 28.

“I have heard out of the Pentagon that there’s a loss of confidence – within the Pentagon,” the senator said. “And of course then everyone here on [Capitol Hill] hears those same concerns.”

Several Republicans have expressed declining confidence in Hegseth, but the reasons for dissatisfaction differ.

Hegseth’s decision to nominate General Christopher LaNeve for US Army chief of staff this week was just the latest source of friction between party members and the administration of President Donald Trump.

Iowa Senator Joni Ernst and others put forward their objections to the nomination, which required unanimity to be endorsed, US media reported. LaNeve faced criticism for lacking experience when he was appointed as acting army chief of staff in April, when Hegseth fired General Randy George without explanation.

Senator Roger Wicker, who serves as chairman of the Senate Armed Services Committee, also questioned LaNeve’s nomination to be the army’s top officer. Last year, after Trump ordered US forces to strike small boats in the Caribbean that he claimed were trafficking drugs, Wicker and Democratic Senator Jack Reed requested that Hegseth clarify the legal basis for mandating the strikes, which experts have questioned .
