Defense Secretary Pete Hegseth said Tuesday that the White House believes it possesses all necessary authorities to continue the conflict with Iran.

The exchange underscores a potential constitutional tension between executive war powers and the congressional role in authorizing prolonged military engagements. If the administration bypasses legislative approval, it may face legal challenges regarding the War Powers Resolution.

During a Senate Appropriations Committee hearing in Washington, D.C., Sen. Lisa Murkowski (R-Alaska) questioned Hegseth on whether the Trump administration still maintains that congressional authorization is not required to sustain the conflict [1]. Murkowski sought to clarify if the executive branch is effectively restarting a clock on military actions without a formal vote from lawmakers [1].

Hegseth said that the White House believes it has "all the authorities necessary at this moment" [1]. He did not elaborate on the specific legal statutes or previous authorizations the administration is citing to justify these operations [1].

Murkowski challenged this position by citing historical precedent regarding military funding and authorization [1]. She pointed to a $6 billion [2] supplemental funding request made by the Clinton administration to continue military operations related to Iran as a marker for how such conflicts are typically managed through legislative oversight [2].

The senator's line of questioning suggests a concern that the current administration may be interpreting executive authority more broadly than previous presidents [1]. By referencing the Clinton-era request, Murkowski highlighted a traditional pattern where the executive branch seeks explicit financial, and legal backing from Congress to ensure the legitimacy of long-term military campaigns [2].

Hegseth said the administration's stance throughout the hearing, affirming that the current legal framework allows the U.S. to proceed with its objectives in the region [1].

The White House believes it has “all the authorities necessary at this moment.”

This exchange highlights a recurring debate over the War Powers Resolution and the extent of a president's ability to conduct hostilities without a formal declaration of war. By asserting that the White House already possesses the necessary authorities, the Trump administration is signaling a preference for executive flexibility over legislative constraints, which may lead to increased friction with members of both parties who favor strict congressional oversight of military spending and engagement.
