Senator Tim Kaine Pushes Bill to Block Trump From Unilateral Iran Military Action

U.S. Senator Tim Kaine (D-VA) introduced legislation on Monday to block former President Donald Trump from launching military action against Iran without Congressional approval. The move comes amid escalating violence between Israel and Iran, raising concerns of a wider conflict that could pull the U.S. into another Middle East war.

Kaine, a long-time advocate for Congressional war powers, emphasized that the U.S. Constitution grants Congress—not the president—the authority to declare war. His resolution would require any military action against Iran to be explicitly authorized by Congress through a formal war declaration or specific authorization for the use of force.

“It is not in our national security interest to engage in a war with Iran unless absolutely necessary to defend the United States,” Kaine said. “I’m deeply concerned that the current Israel-Iran escalation could drag the U.S. into another endless conflict.”

Kaine introduced a similar measure in 2020 during Trump’s first term, which passed both the House and Senate with some bipartisan support. However, it ultimately failed to override Trump’s veto.

The latest war powers resolution is considered privileged under U.S. law, meaning the Senate must take it up for a vote.

Tensions have intensified since Israel launched strikes on Iran last Friday, targeting its nuclear and missile programs. Iran retaliated with missile attacks, claiming its nuclear activities are peaceful. The ongoing exchange has resulted in civilian casualties and global alarm, especially among leaders attending the G7 summit in Canada.

Trump, speaking before leaving for the summit, denied U.S. involvement in the conflict but praised Israel’s actions and warned Tehran against targeting American assets. “I hope there’s going to be a deal,” he said. “Sometimes they have to fight it out.”
