Congressional Oversight Under Strain: From Pentagon Accountability on Iran to White House Spending Questions

Senators are blocking three-quarters of Defense Secretary Pete Hegseth's travel budget until he releases the full investigation into the February 28 missile strike that killed more than 165 people at an Iranian elementary school. Democrats say the White House quietly shifted more than $350 million earmarked for Secret Service hiring to help fund a $600 million ballroom Congress already rejected. And on June 4, the House voted 324-92 against ordering U.S. troops out of Lebanon—117 Democrats joining Republicans in opposition. Three distinct constitutional mechanisms for constraining executive power, all being tested simultaneously, each one revealing whether Congress still possesses tools that produce actual compliance or merely the appearance of oversight.

Three Different Leverage Points, Three Different Standards for Compliance

A bipartisan group of senators has written language into the National Defense Authorization Act that would restrict Hegseth's travel budget to no more than 25 percent of normal funding until he hands over unredacted civilian harm investigations and unedited videos of boat strikes on designated narcoterrorist organizations.

The Pentagon has determined the United States was responsible for the Tomahawk missile attack on the Minab school, which killed at least 156 civilians including 120 schoolchildren (mostly girls aged 7-12), 26 teachers, and 7 parents between 10:23 and 10:45 a.m. on the first day of the 2026 Iran war. The strike resulted from outdated coordinates provided by the Defense Intelligence Agency.

Senator Kirsten Gillibrand, joined by 24 Senate Democrats, has called for a bipartisan investigation and public hearing into the strike. Gillibrand stated that it is "absolutely unacceptable" that one of our missiles hit a school, killing dozens of children, and vowed to continue demanding answers until the American people get the transparency they deserve and processes are implemented to avoid similar tragedies in the future.

Senators Elizabeth Warren and Chris Van Hollen led 11 Democrats in a seven-page letter questioning Hegseth's cuts to Pentagon civilian casualty mitigation offices. The letter cited more than 1,700 civilian deaths from attacks on civilian infrastructure in Iran since late February, including strikes on over 20 schools and a dozen health care facilities, and accused Hegseth of cutting over 90 percent of civilian harm mitigation staffing.

Senator Warren argued that following the laws of war helps set the United States apart from terrorists and adversaries like Russia, which has targeted civilians in Ukraine, and that the U.S. military does not target innocent civilians because it is both right and effective. She added that Secretary Hegseth's outspoken disregard for the rules of war endangers U.S. troops, and his firing of the top military lawyers of the Army, Navy, and Air Force and plans to reduce JAG leadership rank from three-star to two-star are deeply concerning.

On the ballroom front, approximately 150 Democratic lawmakers filed a legal brief in ongoing litigation asserting that the Trump administration cannot demolish or construct new facilities at the White House without clear congressional authorization and explicit appropriation of funds. The brief argues that the Constitution grants Congress exclusive control over federal property and that privately funded large-scale construction and any implied use of public resources circumvent Congress's power of the purse, especially after a federal judge ruled in March that construction could not proceed without congressional approval.

Democrats argue the surprise funding shift revives constitutional clashes over separation of powers, presidential use of congressionally allocated funds, and the legislature's exclusive authority to appropriate money across the federal government.

The Trump administration maintains that private donors will fund the actual ballroom while public funds will only cover secure portions of the facility, but a watchdog group found that ballroom donors won $50 billion in new government contracts. Senate Democrats have launched an investigation into pay-to-play corruption, noting that of $200 million collected, only $60 million is tied to specific donors.

Representative Rashida Tlaib introduced the Lebanon War Powers Resolution invoking Section 5(c) of the War Powers Resolution of 1973, arguing that U.S. military coordination with Israeli forces in Lebanon constitutes hostilities requiring congressional authorization. She argued that Congress, not the president, has the authority to declare war, and that the U.S. is supplying Israel with weapons like white phosphorus bombs and providing targeting intelligence, making the U.S. complicit in attacks on civilians, schools, and hospitals.

When the Executive Decides Not to Answer

At a Senate Armed Services Committee hearing, Admiral Brad Cooper acknowledged only one active civilian casualty investigation out of more than 13,000 munitions used in Iran. When questioned about U.S. strikes on Iranian schools and hospitals, Admiral Cooper repeatedly denied corroborated evidence, stating there is "no indication whatsoever" and "no way to corroborate" civilian casualties despite senators citing specific incidents.

Hegseth has repeatedly refused to answer direct questions about civilian casualties from the February 28 school strike, stating only that the incident is under investigation and that the U.S. never targets civilians. In March 2026, he gutted Pentagon offices responsible for mitigating civilian casualties, reducing staff from 200 to fewer than 40, and publicly called rules of engagement "stupid" while advocating for maximum lethality.

President Trump has made contradictory statements about the Minab school strike, initially falsely claiming Iran was responsible, then saying he doesn't know enough, and later acknowledging U.S. responsibility with the phrase "mistakes are made; a war is nasty" while deflecting accountability.

The Historical Pattern

Constitutional law scholars note that while the Constitution explicitly grants Congress the sole power to declare war and control funding, modern presidents have increasingly acted unilaterally, and courts have largely abdicated their role in enforcing War Powers Resolution constraints. Experts observe that effective checks on executive war powers now depend more on political pressure and legislative signaling than on judicial enforcement or statutory compliance.

The War Powers Resolution of 1973 has been used dozens of times but has rarely succeeded in compelling presidential compliance or troop withdrawal. Funding restrictions embedded in defense authorization bills have historically been among Congress's more effective tools because they create concrete compliance mechanisms tied to annual appropriations processes. Congressional power-of-the-purse battles over executive construction and spending have precedent, but outcomes have varied widely based on political alignment, public attention, and judicial willingness to enforce appropriations constraints.

Are These Actions Real or Theater?

The Lebanon vote provides perhaps the starkest evidence of atrophy: Congress had a clear constitutional tool to constrain executive military action and chose not to use it by an overwhelming margin. Admiral Cooper's flat denials despite documented strikes, Hegseth's refusal to answer direct questions, and ongoing ballroom funding questions despite a court ruling all suggest oversight that generates letters and hearings but rarely forces meaningful compliance when the administration chooses to resist.

Senators Warren and Van Hollen argued that thousands of innocent lives have been lost following the Trump administration's dismantling of programs designed to avert civilian harm, and that Hegseth's disorder and incompetence pose a threat to both civilians and U.S. forces, demanding answers and accountability immediately. Their coalition letter called on the administration to immediately end the war in Iran and fully restore congressionally authorized programs and staffing to mitigate civilian harm, framing civilian protection as central to effective military operations and what differentiates the United States from adversaries.

But evidence cuts both ways. The Hegseth travel restriction is bipartisan and embedded in must-pass defense legislation. Seven Republicans joined Democrats in blocking the ballroom. A federal court sided with Congress on appropriations authority. These are not purely symbolic gestures.

What to Watch

The NDAA with the Hegseth travel restriction must pass both chambers and be signed into law—the first concrete benchmark is whether the restriction survives conference committee negotiations and presidential signature. If enacted, watch whether the Pentagon actually delivers unredacted civilian harm investigations or submits heavily redacted documents, delays indefinitely, or claims national security exemptions.

The ballroom litigation will show whether a federal court ruling and congressional opposition can actually halt construction, or whether the administration proceeds through creative funding arrangements and private-public blending.

Monitor whether Hegseth faces any consequences—confirmation delays for subordinate appointments, sustained funding restrictions, formal censure, or calls for resignation—or whether the controversy fades without institutional accountability. Watch whether the Pentagon implements systemic changes to targeting procedures or treats the Minab strike as an isolated incident.

The ultimate measure will be whether any of these three oversight efforts produce changed executive behavior: restored civilian harm mitigation programs, halted ballroom construction, or altered military engagement rules—or whether they remain gestures that the administration weathers and ignores.
