Congress Failed Again to Stop Trump’s Iran War. This Group Is Trying Through the Courts.

“It is all hands on deck to stop this full-blown constitutional crisis,” said the head of NIAC Action, which filed suit on behalf of Iranian Americans.

Iran attacked US military targets in the Middle East on August 31 in retaliation for American strikes on an island in the Strait of Hormuz, the first exchange of fire for a month in a war that has engulfed the region. Six months into the conflict, the two sides remain at an impasse, with Iran keeping the strategic strait shut and Washington persisting with a naval counter-blockade of Iran.

With Congress unable to rein in President Donald Trump’s war against Iran through legislative action, a group advocating for diplomacy filed a lawsuit against the Trump administration arguing the military action violates the Constitution.

National Iranian American Council Action on Thursday filed its suit in a Washington federal court asking a judge to declare the war on Iran illegal on the basis that it violates the Declare War Clause of the Constitution.

“Can one person decide, on his own, to keep an entire nation at war?”

“No President should have the power to take this country into an indefinite war by himself,” NIAC President Jamal Abdi said in a statement. “Congress never authorized this war. Yet Iranian families are being bombed, American service members have been killed, and communities on both sides are being forced to bear the consequences. This lawsuit asks a fundamental question: Can one person decide, on his own, to keep an entire nation at war?”

The lawsuit was filed as the Senate prepared to vote on a resolution seeking to stop the war. A floor vote on the resolution, which already passed the House of Representatives, failed in the upper chamber Thursday afternoon after senators shot it down in a 49–50 split.

“We’ve unfortunately seen this Congress fail its job of standing up for their constitutional role as the sole body empowered to declare war,” Abdi told The Intercept. “That’s why we are pursuing every option at our disposal, including taking the challenge against this unconstitutional war to the courts.”

Both the Senate vote and NIAC Action’s lawsuit took on new urgency after Trump used his United Nations General Assembly speech on Tuesday to threaten to “annihilate” Iran, a country of 90 million people.

“When Trump is threatening annihilation of another country in a war of aggression,” Abdi said, “it is all hands on deck to stop this full-blown constitutional crisis before it gets worse.”

The White House did not immediately respond to a request for comment.

Seven Months of War

Trump, in partnership with the Israeli military, launched the war against Iran on February 28 with a sudden barrage of airstrikes and missile attacks that left numerous top Iranian leaders dead and killed hundreds of civilians. The early days of the attack saw a missile strike on a school in the town of Minab that killed more than 100 children, which the United Nations declared to be a possible war crime.

It was days later, on March 2, that Trump notified Congress of the initiation of hostilities. In the ensuing months, the war has turned into a regional conflagration. Israel invaded Lebanon, leaving thousands of people killed and tens of thousands more displaced.

Meanwhile, retaliatory missile and drone strikes by Iran against the U.S., Israel, and their allies in the Persian Gulf have severely impacted the region and led to a shutdown of the Strait of Hormuz that has hobbled global fuel markets. And missile fire from the Houthis, the militant group that controls much of Yemen, shut down shipping through the Red Sea’s Bab al-Mandab Strait, further straining the global economy and spurring a Saudi military response.

The initial attacks, thousands of deaths, and cascading economic fallout of the war all took place without the consent of the American people, a fact that NIAC Action’s attorneys cast in the lawsuit as a clear violation of Article 1, Section 8 of the Constitution, which grants Congress the exclusive power to declare war.

“The Constitution does not permit a President to wage war indefinitely and ask Congress for permission later,” said attorney Alan Morrison. “Congress never authorized this war, yet months later the bombing and blockade continued. We are asking the Court to enforce the constitutional line between the President’s authority as Commander in Chief and Congress’s exclusive authority to take the country to war.”

“Calling a war a ‘military operation’ or an ‘excursion’ does not erase the Declare War Clause.”

Though Trump has sought to bypass Congress in pursuing the war through the use of semantics, he has repeatedly undermined that effort with public statements declaring that his military action is a war, NIAC Action’s complaint noted.

“Calling a war a ‘military operation’ or an ‘excursion’ does not erase the Declare War Clause,” said attorney Bruce Fein in a statement. “The question before the Court is whether the President can continue these hostilities without the authorization the Constitution requires.”

The lawsuit was filed on behalf of several NIAC Action members who have been personally impacted by the war. Several of their family members have been killed, wounded, or otherwise terrorized by the monthslong campaign of airstrikes carried out by the U.S. and its allies. One member joining the suit, Nilma Dilmaghani, described the horror of learning that a cousin had been badly wounded in an airstrike that destroyed a family apartment.

“When I learned that my cousin had been trapped under the rubble, that they had lost their home and suffered such serious injuries, I felt completely helpless,” said Dilmaghani. “It is unbearable to watch your family live through this from thousands of miles away and know there is nothing you can do to keep them safe.”

IT’S EVEN WORSE THAN WE THOUGHT.

What we’re seeing right now from Donald Trump is a full-on authoritarian takeover of the U.S. government. 

This is not hyperbole.

Court orders are being ignored. MAGA loyalists have been put in charge of the military and federal law enforcement agencies. The Department of Government Efficiency has stripped Congress of its power of the purse. News outlets that challenge Trump have been banished or put under investigation.

Yet far too many are still covering Trump’s assault on democracy like politics as usual, with flattering headlines describing Trump as “unconventional,” “testing the boundaries,” and “aggressively flexing power.” 

The Intercept has long covered authoritarian governments, billionaire oligarchs, and backsliding democracies around the world. We understand the challenge we face in Trump and the vital importance of press freedom in defending democracy.

IT’S BEEN A DEVASTATING year for journalism — the worst in modern U.S. history.

We have a president with utter contempt for truth aggressively using the government’s full powers to dismantle the free press. Corporate news outlets have cowered, becoming accessories in Trump’s project to create a post-truth America. Right-wing billionaires have pounced, buying up media organizations and rebuilding the information environment to their liking.

In this most perilous moment for democracy, The Intercept is fighting back. But to do so effectively, we need to grow.
