Trump clashes with Senate Republicans over Iran War framework as Congress votes on War Powers

May 24, 2026

President Donald Trump clashed sharply with Senate Republicans during a June 24, 2026 Capitol lunch, highlighted by a shouting match with Senator Bill Cassidy over the Iran war. The confrontation followed a historic 50-48 Senate vote to restrict Trump's war powers. Seeking leverage, Trump cancelled a signing ceremony for a bipartisan housing bill, conditioning his signature on the passage of the stalled Save America Act. Although the administration requested $70 billion for the conflict, intensive lobbying successfully flipped key GOP votes to defeat a subsequent war powers motion.
