‘Trump is no king’: Mark Ruffalo urges Congress to vote on Iran action amid strike speculation

LOS ANGELES, CALIFORNIA: Actor Mark Ruffalo recently took to X to criticize the Trump administration's potential military actions against Iran. He warned that any such action would likely escalate into a full-scale war and urged lawmakers to step in and hold a formal debate before putting soldiers in danger.

Ruffalo was supporting a move by Representative Ro Khanna, who stated that "Trump officials" are suggesting "there's a 90% chance of strikes on Iran."

Ruffalo made it very clear that he does not believe the president has the authority to act alone, stating, "Trump is no King."

His main point is that Congress has a duty to discuss the pros and cons of going to war rather than allowing the executive branch to decide on its own. He is backing Representative Ro Khanna’s plan, who stated on social media, "He can’t without Congress. Rep Thomas Massie and I have a War Powers Resolution to debate & vote on war before putting US troops in harm’s way. I will make a motion to discharge to force a vote on it next week."

It should be noted that Representative Ro Khanna and Representative Thomas Massie are pushing for a vote on a "War Powers Resolution" to ensure Congress has the final say.

In his message, the actor argued that the US should think twice before starting a new conflict in a region that has already suffered from prolonged instability.

He wrote, "Make no mistake. It will be a war. Do we want another war going on in a region that has been torn by war and strife?"

He pointed to past conflicts such as Vietnam, Iraq, Afghanistan, and the situation in Palestine as examples, calling them "disasters of war" that the US should learn from rather than repeat.

Ruffalo also expressed frustration, describing these conflicts as "a bloody stain on America’s soul," while stating, "every one an amoral disaster of weapons manufacturer’s making."
