The U.S. Senate is set to vote on a resolution that would restrict President Donald Trump from taking further military action against Venezuela without explicit congressional authorization.
The vote comes days after U.S. forces captured Venezuelan President Nicolas Maduro during a military raid in Caracas, intensifying scrutiny of the administration’s actions.
Supporters of the measure say it could pass narrowly, reflecting growing unease among some lawmakers over the scope and direction of U.S. involvement in Venezuela.
The resolution is part of a series of war powers efforts introduced since the administration escalated pressure on Venezuela with maritime strikes beginning in September.
Previous measures have failed, though the most recent Senate vote fell just short, signaling a closely divided chamber.
The resolution is co-sponsored by Democratic Senator Tim Kaine of Virginia and Republican Senator Rand Paul of Kentucky.
Paul said some Republicans who previously opposed the measure are reconsidering their positions ahead of the vote.
"I spoke to at least two Republicans today who did not vote for this resolution previously who are thinking about it," Paul said at a news conference.
Kaine argued that recent actions demonstrate sustained military engagement rather than a limited operation.
"This is not a surgical arrest operation by any stretch," Kaine said.
Democratic lawmakers have accused the administration of misleading Congress, noting earlier assurances that there were no plans for regime change or strikes on Venezuelan territory.
Opponents of the resolution argue that Maduro’s seizure constitutes a law enforcement action and falls within the president’s authority as commander-in-chief.
They also contend that limited military actions are justified on national security grounds.
Even if the Senate approves the resolution, significant obstacles remain before it could become law.
The measure would need to pass the Republican-led House of Representatives and overcome an expected presidential veto.
Overriding a veto would require two-thirds majorities in both chambers of Congress.
Lawmakers backing the resolution acknowledge these challenges but say concerns are growing over the prospect of a prolonged and costly campaign in Venezuela.
Trump has defended his approach and recently called for a substantial increase in the U.S. military budget.
The debate highlights enduring tensions between Congress and the White House over war powers and the constitutional role of lawmakers in authorizing military force.
