Republican lawmakers are struggling to gather votes to dismiss a war powers resolution that would require President Trump to withdraw from the war with Iran. The House of Representatives delayed the vote due to insufficient Republican support, highlighting a decline in backing for Trump's military actions. Frustration is growing among lawmakers as the war continues without congressional approval, and some Republicans are beginning to oppose the president's approach. The situation is complicated by the War Powers Resolution of 1973, which mandates congressional approval after 60 days of military engagement.
