The House is preparing to vote Thursday on a war powers resolution to halt President Donald Trump's attack on Iran, a sign of unease in Congress over the rapidly widening conflict that is reordering U.S. priorities at home and abroad.

It's the second vote in as many days, after the Senate defeated a similar measure along party lines. Lawmakers are confronting the sudden reality of representing the American people in wartime and all that entails — with lives lost, dollars spent and alliances tested by a president's unilateral decision to go to war with Iran.

The tally in the House is expected to be tight, but the outcome will provide an early snapshot of the political support, or opposition, to the U.S.-Israel military operation and Trump's rationale for bypassing Congress, which alone has the power to declare war.

"Donald Trump is not a king, and if he believes the war with Iran is in our national interest, then he must come to Congress and make the case," said Rep. Gregory Meeks, the top Democrat on the House Foreign Affairs Committee.

Meeks said in his nearly three decades in Congress, the hardest votes he has taken have been deciding whether to send U.S. troops to war.

The roll calls are a clarifying moment for the president and the parties just days into the overseas conflict that has quickly carried echoes of the long U.S. wars in Afghanistan and Iraq. Many veterans of those wars have since run for office and now serve in Congress.

Trump's Republican Party, which narrowly controls the House and Senate, largely sees the conflict with Iran not as the start of a new war, but the end of a regime that for decades has long menaced the West. The operation has killed Iran's Supreme Leader Ayatollah Ali Khamenei, which some view as an opportunity for regime change, though others warn of a chaotic power vacuum.

Rep. Brian Mast of Florida, the GOP chairman of the House Foreign Affairs Committee, publicly thanked Trump for taking action against Iran, saying the president is using his own constitutional authority to defend the U.S. against the "imminent threat" the country posed.

Mast, an Army veteran who worked as a bomb disposal expert in Afghanistan, said the war powers resolution was effectively asking "that the president do nothing."

For Democrats, Trump's war with Iran, influenced by Israeli Prime Minister Benjamin Netanyahu, is a war of choice that is testing the balance of powers in the U.S. Constitution.

"The framers weren't fooling around," said Rep. Jamie Raskin, D-Md., arguing that the Constitution is clear that only Congress can decide matters of war.

He said whether lawmakers support or oppose the Trump administration's military action, they should have the debate. "It's up to us, we've got to vote on it."

While views in Congress are largely falling along party lines, there are crossover coalitions. Both the House and Senate resolutions were bipartisan, and are drawing bipartisan support and opposition. The House is also voting on a separate resolution affirming that Iran is the largest state sponsor of terrorism.

The war powers resolution, if signed into law, would immediately halt Trump's ability to conduct the war unless Congress approved the military action. The president would likely veto the measure.

As an alternative, a small group of Democrats has proposed a separate war powers resolution that would allow the president to continue the war for 30 days before he must seek congressional approval. It is not expected to come yet for a vote.

After launching a surprise attack against Iran on Saturday, Trump has scrambled to win support for a conflict that Americans of all political persuasions were already wary of entering. Trump administration officials spent hours behind closed doors on Capitol Hill this week trying to reassure lawmakers that they have the situation under control.

Six U.S. military members were killed over the weekend in a drone strike in Kuwait, and Trump has said more Americans could die. Thousands of Americans abroad have scrambled for flights, many lighting up the phone lines at congressional offices as they sought help trying to flee the Middle East.

Defense Secretary Pete Hegseth said that the war could extend eight weeks, twice as long as the president first estimated. Trump has left open the possibility of sending U.S. troops into what has largely been a bombing campaign by air. Hundreds of people in the region have died.

The administration said the goal is to destroy Iran's ballistic missiles that it believes are shielding its nuclear program. It has also said Israel was ready to act against Iran, and American bases would face retaliation if the U.S. did not strike first. On Wednesday, the U.S. said it torpedoed an Iranian warship near Sri Lanka.

The Supreme Court cleared the way Monday for California schools to tell parents if their children identify as transgender without getting the student's approval, granting an emergency appeal from a conservative legal group.

The order blocks for now a state law that bans automatic parental notification requirements if students change their pronouns or gender expression at school.

The split decision comes after religious parents and educators challenged California school policies aimed at preventing schools from outing students to their families. Two sets of Catholic parents represented by the Thomas More Society say it caused schools to mislead them and secretly facilitate the children's social transition despite their objections.

California, on the other hand, argued that students have the right to privacy about their gender expression, especially if they fear rejection from their families. The state said that school policies and state law are aimed at striking a balance with parents' rights.

The high court majority, though, sided with the parents and reinstated a lower-court order blocking the law and school policies while the case continues to play out.

"The parents who assert a free exercise claim have sincere religious beliefs about sex and gender, and they feel a religious obligation to raise their children in accordance with those beliefs. California's policies violate those beliefs," and burden the free exercise of religion, the majority wrote in an unsigned order.

The court's three liberal justices publicly dissented, saying the case is still working its way through lower courts and there was no need to step in now. "If nothing else, this Court owes it to a sovereign State to avoid throwing over its policies in a slapdash way, if the Court can provide normal procedures. And throwing over a State's policy is what the Court does today," Justice Elena Kagan wrote.

Conservative Justices Samuel Alito and Clarence Thomas, meanwhile, noted they would have gone further and granted teachers' appeal to lift restrictions for them.

The Thomas More Society called the decision "the most significant parental rights ruling in a generation."

California Gov. Gavin Newsom's office defended the law, saying teachers should be focused on instruction, not required "to be gender cops."

The order "undermines student privacy and the ability to learn in a safe and supportive classroom, free from discrimination based on gender identity," said Marissa Saldivar, a spokesperson for the Democratic governor.

The Supreme Court has ruled for religious plaintiffs in other recent cases, including allowing parents to pull their children from public-school lessons if they object to storybooks with LGBTQ+ characters.

The California order comes months after the court upheld state bans on gender-identity-related healthcare for minors. The justices also seem to be leaning toward allowing states to ban transgender athletes from playing on girls sports teams.

School policies for transgender students, meanwhile, have also been on the court's radar in other cases. The court rebuffed another similar case out of Wisconsin in December, but three conservative justices indicated they would have heard the case. Justice Samuel Alito called the school policies "an issue of great and growing national importance."

The justices have been weighing whether to hear arguments in cases out of states like Massachusetts and Florida filed by other parents who say schools facilitated social transition without informing them.

The Trump administration, meanwhile, found in January that California's policies violated parents' right to access their children's education records. The Justice Department also sued after determining the states' transgender athlete policies violate federal civil rights law.

As U.S. and Israeli forces pounded Iran, and Tehran and its affiliates retaliated by firing missiles at targets across the Mideast on Monday, the international legal order was caught in the crossfire.

At the heart of the post-World War II global order — United Nations headquarters in New York — Secretary-General António Guterres told the Security Council on Saturday that U.S. and Israeli airstrikes violated international law, including the U.N. Charter. He also condemned Iran's retaliatory attacks for violating the sovereignty and territorial integrity of nations in the Mideast.

Officials in the Trump administration insist that the military campaign is a lawful measure to ensure Tehran does not build nuclear weapons. "It's a matter of global security. And to that end, the United States is taking lawful actions," Trump's U.N. ambassador, Mike Waltz, said.

Iranian Foreign Minister Abbas Araghchi wrote in a letter to the U.N. on Sunday that the killing of Supreme Leader Ayatollah Ali Khamenei "constitutes a grave and unprecedented breach of the most fundamental norms governing relations among States."

On Monday, Defense Secretary Pete Hegseth bullishly defended the U.S. military campaign. "No stupid rules of engagement, no nation building quagmire, no democracy building exercise, no politically correct wars. We fight to win and we don't waste time or lives," he said at the Pentagon.

The war with Iran comes less than two months after U.S. forces swooped into Caracas to capture former Venezuelan President Nicolás Maduro and fly him to New York to face justice.

David Crane, an American expert on international law and founding prosecutor of a United Nations court that prosecuted crimes in Sierra Leone, wrote in an analysis that U.S. attacks in Iran and Venezuela "highlight a dangerous trend: the normalization of unilateral force as a tool of foreign policy. Even when the outcome is positive, the violation of international law and constitutional limits sets a precedent that threatens global stability and undermines America's own legal foundations."

In Washington, many Democrats have called the strikes illegal. They argue that under the Constitution, only Congress has the power to declare war. They say the Trump administration failed to lay out its rationale or plan for the military strikes, and the aftermath.

Congress hurriedly scheduled a war powers debate for Monday over Trump's authority to bomb Iran.

The Trump administration's latest policy of deporting immigrants to "third countries" to which they have no ties is unlawful and must be set aside, a federal judge ruled Wednesday in a case that already reached the nation's highest court.

U.S. District Judge Brian E. Murphy in Massachusetts agreed to suspend his decision for 15 days, giving the government time to appeal his latest ruling in the case. Murphy noted that the U.S. Supreme Court ruled in the administration's favor last year, pausing Murphy's previous decision and clearing the way for a flight carrying several migrants to complete its trip to war-torn South Sudan, where they had no ties.

Murphy said migrants challenging the Department of Homeland Security's policy have the right to "meaningful notice" and an opportunity to object before they are removed to a third country. The policy "extinguishes valid challenges to third-country removal by effecting removal before those challenges can be raised," the judge concluded.

"These are our laws, and it is with profound gratitude for the unbelievable luck of being born in the United States of America that this Court affirms these and our nation's bedrock principle: that no 'person' in this country may be 'deprived of life, liberty, or property, without due process of law,'" Murphy wrote.

In June, the Supreme Court's conservative majority found that immigration officials can quickly deport people to third countries. Liberal justices Sonia Sotomayor and Ketanji Brown Jackson dissented, saying the ruling gives the government special treatment.

Murphy said President Donald Trump's administration has repeatedly violated — or tried to violate — his orders. Last March, he noted, the Defense Department deported at least six class members to El Salvador and Mexico without providing the process required under a temporary restraining order that Murphy issued. DHS issued its new policy guidance for third-country removals on March 30, two days after Murphy's order.

"The simple reality is that nobody knows the merits of any individual class member's claim because (administration officials) are withholding the predicate fact: the country of removal," wrote Murphy, who was nominated to the bench by Democratic President Joe Biden.

Murphy said the DHS third-country removal policy has targeted immigrants who were granted protection from being sent back to their home countries, where they feared being tortured or persecuted in other ways.

Eight men who were sent to South Sudan in May had been convicted of crimes in the U.S. and had final orders of removal, Immigration and Customs Enforcement officials have said.

The Supreme Court said that it will hear from oil and gas companies trying to block lawsuits seeking to hold the industry liable for billions of dollars in damage linked to climate change.

The conservative-majority court agreed to take up a case from Boulder, Colorado, among a series of lawsuits alleging the companies deceived the public about how fossil fuels contribute to climate change.

Governments around the country have sought damages totaling billions of dollars, arguing it's necessary to help pay for rebuilding after wildfires, rising sea levels and severe storms worsened by climate change. The lawsuits come amid a wave of legal actions in states including California, Hawaii and New Jersey and worldwide seeking to leverage action through the courts.

Suncor Energy and ExxonMobil appealed to the Supreme Court after Colorado's highest court let the Boulder case proceed. The companies argue emissions are a national issue that should be heard in federal court, where similar suits have been tossed out.

President Donald Trump's administration weighed in to support the companies and urge the justices to reverse the Colorado Supreme Court decision, saying it would mean every locality in the country could sue essentially anyone in the world for contributing to global climate change.

Trump, a Republican, has criticized the lawsuits in an executive order, and the Justice Department has sought to head some off in court.

Attorneys for Boulder had agued that the litigation is still in early stages and should stay in state court.
