WASHINGTON — Congressional investigations related to the 2026 conflict involving the United States and Iran continued on Monday, with lawmakers pursuing separate inquiries into the legal basis for military operations, executive branch decision-making and oversight of actions taken during and after the fighting.
Several Senate Democrats have continued pressing the Trump administration to release the legal analysis supporting its assertion that hostilities with Iran had ended, arguing that military operations and the continued deployment of U.S. forces may require additional congressional scrutiny under the War Powers Resolution. In a letter led by Senators Adam Schiff, Tim Kaine and Senate Democratic Leader Chuck Schumer, lawmakers requested the administration disclose an Office of Legal Counsel opinion cited in previous communications with Congress.
The administration has maintained that it complied with statutory reporting requirements and has defended its handling of military operations. The White House has previously stated that its actions were consistent with its constitutional authorities and national security responsibilities.
Congressional attention has also focused on broader oversight questions arising from the conflict. Members of both parties have called for briefings from defense and intelligence officials on military operations, ceasefire implementation and the status of U.S. forces in the region following renewed tensions despite an earlier agreement intended to halt hostilities. United Nations officials have likewise urged all parties to exercise restraint, warning that the ceasefire remains fragile and that further escalation could undermine diplomatic efforts.
Separate oversight efforts unrelated to battlefield operations but tied to administration conduct during the conflict period have also continued. Democratic lawmakers recently announced investigations into potential ethics and conflict-of-interest issues surrounding government decisions affecting private entities, while other congressional committees have opened inquiries into executive branch spending and the use of government resources. Those investigations remain in their preliminary stages, and no findings of wrongdoing have been announced.
The congressional reviews come as lawmakers debate the scope of legislative oversight over military engagements and executive authority. Legal scholars and members of Congress have continued to cite the War Powers Resolution as a central framework for determining whether extended military operations require additional authorization from Congress, while administration supporters argue the president retains broad constitutional authority to respond to national security threats.
As of Monday, no congressional committee had issued final conclusions regarding the conflict-related investigations. Committee leaders said requests for documents, classified briefings and additional testimony remain ongoing as lawmakers continue examining the legal, operational and policy decisions associated with the conflict.
