The U.S. Senate on Wednesday rejected a second attempt by Democrats to limit President Donald Trump’s military operations involving Iran, voting 48–53 against a war powers resolution introduced by Cory Booker. The outcome underscored the difficulty of curbing executive military authority in a Congress where the president’s party holds significant influence.
The vote largely followed partisan lines. However, Rand Paul broke with fellow Republicans to support the resolution, while John Fetterman sided with Republicans in opposing it. The result echoed a previous failed effort led by Tim Kaine, signaling a consistent lack of sufficient support for such measures.
Booker’s resolution argued that the administration had engaged in extensive and ongoing military actions related to Iran without proper congressional authorization. It sought to compel the president to withdraw U.S. forces from hostilities unless Congress formally approved the mission through a declaration of war or a specific authorization for the use of military force. At present, no such authorization exists for operations targeting Iran, making the issue a focal point for debate over constitutional war powers.
Despite the resolution’s failure, Democratic lawmakers are expected to continue introducing similar proposals. These repeated efforts are intended not only to challenge the administration but also to force lawmakers to publicly clarify their positions on congressional oversight of military engagements. A comparable initiative in the House of Representatives has also failed, reinforcing the uphill battle faced by proponents of restricting presidential war-making authority.
At the heart of the debate is the War Powers Resolution, a statute enacted during the Vietnam War era to limit the president’s ability to engage U.S. forces in prolonged conflicts without congressional approval. Presidents from both parties have long criticized the law as unconstitutional, arguing that it infringes on the commander-in-chief’s authority under Article II. The Supreme Court has never definitively ruled on the law’s validity, leaving its enforcement uncertain.
Fetterman has drawn particular attention for his stance. He has consistently opposed Democratic-led efforts to restrict military action and has voiced strong support for the joint U.S.-Israeli campaign. He described the strikes targeting Iran’s nuclear program and leadership as justified and has advocated continued pressure on Iranian leadership until a government emerges that is willing to coexist peacefully and reduce regional threats.
The conflict escalated dramatically following the reported killing of Iran’s Supreme Leader, Ali Khamenei, in coordinated U.S.-Israeli strikes aimed at critical infrastructure and leadership compounds. Reports indicate that his son, Mojtaba Khamenei, was selected as a successor, though his condition and status remain unclear amid further military operations.
Israeli Defense Minister Israel Katz has warned that any new leader associated with the current regime would be targeted, emphasizing that operations will continue aggressively. While Israeli officials have openly supported regime change, U.S. leaders such as Pete Hegseth and Marco Rubio have framed the mission more narrowly, focusing on neutralizing nuclear and missile threats rather than pursuing long-term nation-building.
The repeated failure of these war powers resolutions highlights a persistent struggle between Congress and the executive branch over control of military decisions, a tension that continues to shape U.S. foreign policy as the situation with Iran evolves.
