WASHINGTON — President Trump shrugged off the House passage Wednesday of a resolution that seeks to end the conflict with Iran absent congressional approval.

The anti-war rebuke from the GOP-held House sets up a high-stakes vote in the Senate, where a simple majority is needed to pass the measure and 50 senators already supported a similar resolution in May.

“Yesterday, in a meaningless vote, the House voted, 4 bad Republicans and all of the Dumocrats, to limit my War Powers, right in the middle of my final negotiations to end the War with the Islamic Republic of Iran,” Trump wrote on Truth SocialThursday morning.

“Who would do such an unpatriotic thing. They know where the negotiations stand,” Trump added.

“The Democrats are fueled by Trump Derangement Syndrome. They would rather have our Country fail than give me another, of many, victories. The four Republicans, that’s a whole other story – They’re GRANDSTANDERS! They should be ashamed of themselves. MAGA!!!”

Tom Barrett of Michigan, Warren Davidson of Ohio, Brian Fitzpatrick of Pennsylvania and Thomas Massie of Kentucky voted with 211 Democrats to approve the resolution.

Six other Republicans — Dusty Johnson of South Dakota, Tom Kean Jr. of New Jersey, Morgan Luttrell of Texas, Nancy Mace and Ralph Norman of South Carolina and Andy Ogles of Tennessee — did not vote.

The White House argues the War Powers Resolution, which underpins congressional action, is unconstitutional by infringing on the president’s power to conduct foriegn affairs.

Still, a Senate loss would be a major political blow to Trump.

Courts historically have refused to order presidents to end wars, even if they blatantly ignore the War Powers Resolution’s 60-day deadline to get approval from Congress, as happened with then-President Barack Obama’s intervention in Libya’s civil war.

The 1973 law was adopted after presidents of both political parties secretly expanded the Vietnam War without congressional approval.

The White House argues that it’s not breaking the 60-day rule because of a cease-fire in effect since April 8, even though there have been periodic skirmishes during the truce.

“I’d say in that part of the world, ‘cease-fire’ is when you’re shooting in a more moderate manner,” Trump told reporters in the Oval Office on Wednesday.

Judges have previously ruled that the legislature has its own enforcement power to end wars by withholding funds — meaning additional congressional action is likely needed to actually stop the conflict.

The Iran war began on Feb. 28 — with Trump initially predicting a timeframe of “four weeks or so.” 

Peace talks are focused on an initial memorandum of understanding that would reopen the Strait of Hormuz to shipping while giving additional time to sort out the fate of Iran’s highly enriched uranium.
