Defense Secretary Pete Hegseth faced withering questioning in his first appearance before Congress since the Trump administration went to war against Iran. Skeptical Democrats on Wednesday grilled Hegseth over a costly conflict being waged without congressional approval. The war has cost $25 billion so far. That's according to Pentagon numbers presented to the House Armed Services Committee during a contentious hearing ostensibly focused on the administration’s 2027 military budget proposal. While Republicans focused on the details of military budgeting and voiced support for the Iran operation, Democrats questioned Hegseth about the ballooning costs of the war and the huge drawdown of critical U.S. munitions.
