• Defense Secretary Pete Hegseth testified before the House Armed Services Committee.
• Hegseth faced criticism from Democrats and some Republicans over his handling of the war.
• He called criticism from Democrats and some Republicans 'the biggest adversary' the US faces.
• The hearing was Hegseth's first public testimony since the war in Iran began.

Hegseth's testimony may indicate a deepening divide between the Pentagon and Congress over the Iran war strategy. The criticism he faced suggests that the administration's handling of the conflict could become a significant point of contention, which could impact the war's outcome and the US's international relationships.
