The vote marked a rare bipartisan rebuke of the war, but is mostly symbolic. Democrats have been unable to pass a war powers resolution in the Senate, and even if they could it would likely be vetoed.
As Congress moves toward a potential war powers vote this week, most congressional Republicans are standing behind President Trump’s decision over the weekend to attack Iran, while most Democrats remain opposed to authorizing more conflict.
Democrats and a few Republicans are calling for curbing Trump's unilateral use of military power in Iran, despite previous such efforts failing to advance.
The resolution would have forced President Trump to get authorization from Congress before launching military operations in Venezuela. It was blocked after having previously advanced with GOP support.
