The House has passed a resolution aimed at constraining President Trump Donald John TrumpHR McMaster says president's policy to withdraw troops from Afghanistan is 'unwise' Cast of 'Parks and Rec' reunite for virtual town hall to address Wisconsin voters Biden says Trump should step down over coronavirus response MORE’s ability to take military action against Iran, sending it to the president’s desk for his expected veto.

In a largely party-line 227-186 vote, the House approved the resolution that would direct the president to “terminate the use of United States Armed Forces for hostilities against” Iran unless Congress specifically authorizes it. Six Republicans voted for the measure.

The Senate passed the resolution in a 55-45 vote last month, with eight Republicans siding with Democrats to support it. Neither chamber of Congress is expected to have the votes to override Trump’s likely veto.

The passage of the resolution comes after tensions with Iran spiked earlier this year to the point where Washington and Iran appeared to be on the brink of war.

U.S.-Iran tensions have risen since Trump withdrew from the Iran nuclear deal in 2018 and reimposed harsh sanctions.

But hostility skyrocketed in early January with a U.S. drone strike that killed top Iranian Gen. Qassem Soleimani.

Iran responded with a rocket attack on two military bases in Iraq housing U.S. troops. More than 100 U.S. troops were later diagnosed with traumatic brain injuries caused by the attack.

Since the strikes, both sides have stepped back from the brink. But just before the House started voting Wednesday, the U.S. military confirmed that 15 rockets hit Camp Taji in Iraq, and several reports said that two Americans and a British service member were killed.

Officials have not placed blame for the attack, but suspicion immediately fell on Iran-backed militias that operate in Iraq.

During floor debate on the measure, some Republicans argued the resolution is no longer relevant.

“It orders the president to terminate hostilities against Iran. The problem is, for the other side, we are not engaged in hostilities in Iran,” McCaul said.

But supporters of the war powers resolution argued it is still necessary to assert Congress’ constitutional authority over declaring war.

“Congress doesn’t have to wait until the president alone decides to use military force again,” Engel said ahead of the vote. “Indeed, it’s our responsibility to do something. Because we know that tensions could flare up again at a moment’s notice, Iran has not been deterred as the administration promised.”

McCaul on Wednesday also attacked Democrats for bringing the resolution up for a vote while the nation is gripped by fear over coronavirus, arguing constituents he’s spoken to recently have asked about the virus and “were really not concerned about the war powers resolution.”

The Trump administration has defended the Soleimani strike as necessary to “reestablish deterrence” with Iran. Administration officials have also claimed, without providing evidence, that Soleimani was planning “imminent” attacks.

Democrats have blasted the administration’s shifting explanations for the drone strike and failure to provide evidence on Soleimani’s alleged plots.

The House previously passed a similar resolution in January a week after the Soleimani strike. The main difference between that measure and the one passed Wednesday is the type of resolution. The January resolution would not have had to get Trump’s signature, but that also raised questions about whether it would be binding.

The White House has threatened to veto the measure, saying it “fails to account for present reality.” Ahead of last month’s Senate vote on the resolution, Trump also urged senators to vote against by arguing it would “show weakness.”
