Republican Party divisions are surfacing as Congress prepares to vote on war powers resolutions concerning President Trump's extensive U.S. and Israeli military operations against Iran, launched over the weekend. While some Republicans, like Reps. Thomas Massie and Sen. Rand Paul, are criticizing the strikes for lacking congressional authorization and deviating from an "America First" agenda, others, including House Speaker Mike Johnson, defend the president's actions as a necessary defensive measure. The conflict has already resulted in six American service member deaths and eighteen wounded, with officials predicting further casualties and a campaign potentially lasting four to five weeks. The administration cites Iran's ballistic missile program and stalled nuclear negotiations as justifications, though intelligence did not suggest an imminent Iranian preemptive strike.
