President Donald Trump rejected the war powers resolution approved by the House on Wednesday, calling it "meaningless."
In a social media publication, Trump also slammed the four Republican lawmakers who voted along Democrats to pass the measure "right in the middle of my final negotiations to end the War with the Islamic Republic of Iran."
"Who would do such an unpatriotic thing. They know where the negotiations stand. 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," Trump added.
The vote in question was the first time the House passed such a resolution since the war began. The four GOP Reps. who voted in favor were Thomas Massie of Kentucky, Brian Fitzpatrick of Pennsylvania, Tom Barrett of Michigan and Warren Davidson of Ohio.
Democratic Rep. Jared Goldman of Maine also dropped his opposition to the initiative, marking the first time the party voted unanimously in favor after three attempts.
The Upper House approved for the first time such a resolution after Louisiana Senator Bill Cassidy flipped his vote following his defeat in the Republican primary.
Cassidy joined Rand Paul, Susan Collins and Lisa Murkowski in backing the resolution. The final vote was 50-47, as John Fetterman was again the lone Democrat who voted against it.
"While I support the administration's efforts to dismantle Iran's nuclear program, the White House and Pentagon have left Congress in the dark on Operation Epic Fury," Cassidy said in a social media publication after the vote. "Until the administration provides clarity, no congressional authorization or extension can be justified."
However, despite the vote's passing, it is not clear whether Trump would comply with it, considering that the White House has claimed that hostilities have technically ceased because there is a ceasefire.
The House's resolution was introduced in April by Rep. Gregory Meeks of New York, the top Democrat on the House Foreign Affairs Committee. It would direct Trump to "to remove United States Armed Forces from hostilities with Iran" unless given congressional authorization.
Republican Rep. Brian Mast, the chairman of the House Foreign Affairs Committee, called the move a "stupid political vote" that "weakens the president's hands as he's negotiating with Iran."
"We're going to continue to do our constitutional responsibilities," he said after the vote, rejecting accusations that such votes have undermined the Trump administration in negotiations with Iran.
