Thursday‘s vote is largely symbolic, and the resolution will not go to Trump’s desk for signature if the Senate chamber were also to pass it.

But Democrats‘ war powers effort underscores that the war in Iran is continuing to divide Republicans, several of whom have complained the White House has not given enough visibility to Congress about the military’s actions.

Just 34% of voters approve of Trump‘s handling of Iran, according to a Fox News poll released Wednesday.

The 214-208 vote requiring congressional approval for the war comes as the Senate is expected to consider a similar resolution later Thursday morning. Though the votes forced by Democrats are largely symbolic, they are meant as a strong signal to the Republican president that his support on Capitol Hill is chipping away as the war drags on and lawmakers in both parties have questioned his administration’s endgame.

The war has had “no clear mission, no strategy, no end goal,” said Washington Rep. Pramila Jayapal, a Democrat who led the resolution on the House floor.
