Republicans rejected a resolution to curb Trump’s ability to unilaterally take military action, even as questions linger about the scope and goals of the escalating conflict.

Senate Republicans on Wednesday blocked a resolution to curb Donald Trump’s military authority in Iran, sending a clear message to the country and world: GOP lawmakers are — at least for the moment — unwilling to put a check on the president’s operation in the Middle East, and there’s little Democrats can do about it right now.

The 47-53 vote fell mainly along party lines, with Sen. Rand Paul of Kentucky — the GOP co-sponsor of the effort — the only Republican to join all but one Democrat, Sen. John Fetterman of Pennsylvania, in support of the motion.

The measure would direct the removal of U.S. forces from Iran that haven’t been authorized by Congress, pointing to Article I of the Constitution, which gives Congress sole power to declare war.

As the vote was underway, Paul lamented a Congress “without ambition.”
