Five Democratic senators, led by Senator Elizabeth Warren, sent a letter to U.S. Central Command Commander Brad Cooper, requesting an assessment of damage to U.S. military bases, a repair timeline, and details on expenditures for alternative facilities. The military previously estimated that the war had cost $43.6 billion as of September 3, but this figure did not include damage to bases and facilities caused by Iranian attacks. The senators noted that Cooper had shared damage estimates in a classified briefing, arguing there was no reason to keep them classified. Warren reiterated on Twitter that the American people have a right to know the full cost of the Trump administration's unauthorized war with Iran.
