U.S. Senate votes to halt Iran war, bucking Trump

In a dramatic move that directly challenges presidential authority, the U.S. Senate voted on June 23, 2026, to immediately halt military intervention in an ongoing 'Iran war,' setting up a monumental clash over war powers with President Donald Trump. This bipartisan legislative action aims to force a withdrawal of U.S. armed forces from hostilities with Iran, a significant rebuke to the President's foreign policy. This isn't just a political skirmish; it's a constitutional showdown invoking the rarely used War Powers Resolution, which empowers Congress to rein in presidential military actions. President Trump has historically taken a firm stance against Iran, leading to heightened tensions that escalated into the current conflict. The Senate's vote reflects growing discomfort within the legislative branch about the scope and duration of the military engagement, asserting its constitutional role in declaring and funding wars against the executive branch commander-in-chief powers. Now, all eyes are on President Trump, who is widely expected to issue a presidential veto against the resolution. Should he do so, the Senate, and potentially the House, would need to muster a two-thirds majority to achieve a veto override, a high bar for even the most unified Congress. The outcome will not only determine the immediate future of U.S. involvement in Iran but also redefine the balance of power between the executive and legislative branches on matters of national security and military intervention for years to come.
