A prominent Republican lawmaker has formally initiated impeachment proceedings against Defense Secretary Pete Hegseth, leveling a broad series of allegations that accuse the Pentagon chief of subverting the Constitution, bypassing legislative oversight, and infringing upon constitutionally protected speech.
Representative Thomas Massie of Kentucky submitted eight articles of impeachment during a floor session on Tuesday. The resolution centers heavily on the administration's military campaigns abroad, particularly the ongoing war in Iran, while asserting that the defense secretary has systematically circumvented statutory limits placed on executive authority.
Addressing his colleagues from the House floor, Massie argued that Hegseth’s conduct was directly contrary to the public trust placed in the office of the Secretary of Defense. The Kentucky lawmaker asserted that the Pentagon leadership’s actions have undermined constitutional governance, caused significant harm to law and justice, and resulted in manifest injury to the citizens of the United States.
At the core of the resolution is the assertion that Hegseth directly violated the War Powers Resolution of 1973. Enacted during the Vietnam War era, the landmark statute was designed to establish a legislative check on presidential authority by requiring explicit congressional approval before the nation can be committed to extended armed conflicts overseas.
The statute mandates that the executive branch deliver formal notification to Congress within 48 hours of introducing armed forces into active hostilities absent a formal declaration of war. Furthermore, the law imposes a strict 60-day limitation on any unauthorized engagement, providing an additional 30-day period solely for the safe withdrawal of military personnel unless Congress enacts an explicit extension or authorization.
The underlying conflict in Iran began in late February, with the administration initially stating that its early operational phase, dubbed Operation Epic Fury, concluded in early May. President Donald Trump later submitted notification to lawmakers on July 10 that military action had officially recommenced following his declaration that a monthlong ceasefire had ended.
In his resolution, Massie emphasized that lawmakers never authorized the military campaign. The articles highlight that throughout the 60-day statutory window following the administration's transmittal, Congress neither passed a declaration of war nor enacted specific authorization for the use of military force, despite remaining fully capable of convening to discharge its constitutional obligations.
The executive branch has consistently maintained a conflicting legal stance regarding the validity of the War Powers Resolution. President Trump has asserted that congressional authorization is not required to sustain the military campaign in Iran, publicly characterizing the 1973 statute as an unconstitutional constraint on executive power.
While the House has repeatedly voted to pass measures aimed at restricting the administration's war-making capabilities in Iran under the War Powers framework, those legislative initiatives have consistently stalled in the Republican-controlled Senate, preventing any binding statutory limitations from taking effect.
Under the procedural motion filed on Tuesday, House rules dictate that lawmakers must take up a vote on the impeachment articles within a two-day window. Massie acknowledged that he deliberately kept his intention to introduce the resolution secret, explaining that prior disclosure might have prompted House Republican leadership to cancel scheduled legislative days to avoid taking up the measure.
Beyond the overarching war powers disputes, the impeachment articles charge Hegseth with failing to adhere to statutory mandates intended to minimize civilian casualties during military operations. Massie specifically cited an early-war strike that hit an Iranian girls' school, an incident that a preliminary Pentagon review in March concluded was likely caused by U.S. forces, though the site was not intentionally targeted.
The resolution also targets Hegseth over his treatment of political opponents, specifically citing the demotion of Senator Mark Kelly of Arizona. Kelly, a retired Navy captain and Democratic lawmaker, had previously delivered public remarks urging military personnel to refuse any unlawful orders.
Massie’s filing characterizes the demotion as an unlawful abuse of administrative authority, arguing that Hegseth sought to punish a sitting member of the legislative branch for engaging in protected speech while fulfilling official oversight responsibilities. The measure frames the executive action as an improper attempt by one branch of government to penalize a coordinate branch.
The eight articles also encompass several other unilateral military operations undertaken by the administration. Among the grievances listed are U.S. strikes against maritime vessels in the Caribbean, strikes directed at Houthi targets in Yemen, and the capture of former Venezuelan President Nicolas Maduro, which the resolution characterizes as the unlawful kidnapping of a sovereign foreign leader.
Massie has long established himself as a leading anti-interventionist voice within the Republican Party, repeatedly breaking with party leadership to vote alongside Democrats on matters concerning foreign policy and military engagement. His stance placed him in direct opposition to Trump, who endorsed a primary challenger against Massie in Kentucky that defeated the incumbent lawmaker in May.
The Department of Defense strongly rejected the charges outlined in the impeachment measure. In an official statement, Pentagon press secretary Kingsley Wilson defended the defense secretary’s performance, describing Hegseth as a transformative leader focused on cutting through bureaucracy, driving technological innovation, and prioritizing the needs of active-duty service members. Wilson added that the Pentagon remains fully aligned behind Hegseth's strategic vision.
Given the prevailing Republican majority in the House of Representatives, the impeachment resolution faces overwhelming political opposition and is widely considered virtually certain to fail when brought to the floor for a mandatory vote.
