President Donald Trump’s bombardment of three sites in Iran has quickly sparked debate in Congress over his authority to launch the strikes, with Republicans praising Trump for decisive action even as many Democrats warned he should have sought congressional approval. The response came after Trump had publicly mulled the strikes for days and many congressional Republicans had cautiously said they thought he would make the right decision. Senate Majority Leader John Thune said Saturday evening that “as we take action tonight to ensure a nuclear weapon remains out of reach for Iran, I stand with President Trump and pray for the American troops and personnel in harm’s way.”
