Breaking News: U.S. Senate Plans Preliminary Vote on Resolution to Block Further Trump Military Strikes on Iran

The United States Senate is preparing to hold a preliminary vote on a resolution aimed at preventing President Donald Trump from ordering additional U.S. military strikes against Iran without congressional approval, according to reporting by The Washington Post.

The measure, introduced under the War Powers framework, seeks to reassert Congress’s constitutional authority to decide when the United States enters sustained military conflict.

Supporters argue that the resolution would require the president to obtain explicit authorization from lawmakers before continuing or expanding military operations against Iran.

Lawmakers backing the resolution say the move is necessary to prevent the United States from becoming further entangled in a widening conflict in the Middle East.

Several senators have expressed concern that recent military actions were launched without a clear long-term strategy or formal approval from Congress.

Critics of the president’s approach contend that the U.S. Constitution grants Congress—not the president—the power to declare war.

They say allowing continued strikes without legislative oversight risks escalating the conflict and undermining the balance of powers between the executive and legislative branches.

However, many Republican lawmakers have defended the administration’s actions, arguing that the president has the authority as commander-in-chief to respond to threats against U.S. forces and interests in the region.

The vote will serve as one of the first major congressional tests of support for the administration’s military campaign against Iran.

Even if the measure advances, it would still face significant political hurdles in both chambers of Congress and could ultimately be vetoed by the president.

If passed, the resolution could force the administration to halt further military operations against Iran unless lawmakers formally authorize them—setting up a high-stakes clash between Congress and the White House over war powers and U.S. involvement in the escalating conflict.
