Defense Secretary Pete Hegseth is facing eight articles of impeachment after Republican Rep. Thomas Massie of Kentucky launched an extraordinary challenge against a Cabinet official serving under a president from his own party.**
Massie introduced the 34-page impeachment resolution on September 15, 2026, taking to the House floor for more than an hour to read the charges against Hegseth.
The resolution accuses Hegseth of abusing the powers of his office, violating constitutional limits on the use of military force and disregarding laws governing American military operations.
At the center of the impeachment effort is the ongoing U.S. conflict with Iran.
Massie argues that Hegseth directed American forces into hostilities against Iran without a declaration of war or specific authorization from Congress. Several of the articles focus on the War Powers Resolution of 1973 and Hegseth's continuation of military operations despite congressional efforts to restrict them.
But the accusations extend well beyond Iran.
Eight Articles of Impeachment
Massie's resolution lays out eight separate allegations against Hegseth.
The articles address the use of American military force against Iran without congressional authorization; continuing those operations despite congressional action seeking their termination; alleged violations of statutory War Powers deadlines; and accusations that Hegseth weakened or ignored safeguards intended to minimize civilian casualties.
Another article targets lethal military strikes against suspected drug-trafficking vessels, which Massie characterizes as extrajudicial killings rather than legitimate law-enforcement operations.
The resolution also accuses Hegseth of suppressing constitutionally protected speech in connection with the Pentagon's actions against Democratic Sen. Mark Kelly of Arizona. Kelly participated in a video reminding military and intelligence personnel that they are obligated to refuse illegal orders.
Massie additionally challenges the legality of the U.S. military operation that resulted in the capture of Venezuelan leader Nicolás Maduro and his wife, arguing that the operation lacked constitutional or legal authorization.
The final article concerns American military strikes in Yemen, which Massie alleges violated war-powers requirements and resulted in civilian deaths.
A Republican Challenges His Own Party
The political circumstances surrounding the impeachment effort make it particularly unusual.
Massie is a Republican challenging the defense secretary of a Republican administration.
He has repeatedly clashed with President Donald Trump over presidential war powers, foreign military involvement and other issues. Earlier in 2026, Massie lost his Republican primary to a Trump-backed challenger and is expected to leave Congress when his term expires.
Hegseth himself had campaigned against Massie during that primary.
Massie has said his impeachment effort is not dependent upon whether enough members of Congress ultimately vote to remove Hegseth. He described the resolution as an attempt to establish a congressional record of what he considers unconstitutional conduct by the administration.
Pentagon Defends Hegseth
The Pentagon rejected Massie's characterization of Hegseth's tenure.
Pentagon press secretary Kingsley Wilson defended the secretary following the filing, calling Hegseth a transformative leader and saying the department remains united behind his leadership.
The allegations contained in the impeachment resolution remain accusations made by Massie; filing articles of impeachment does not establish that Hegseth committed the offenses alleged.
House Vote Delayed
Massie filed the resolution as a privileged measure, a procedural designation that ordinarily requires the House to address it quickly.
That initially raised the possibility of a House vote before lawmakers left Washington.
Instead, Republican House leadership canceled the chamber's final scheduled legislative day before its pre-election recess. That prevented the anticipated vote from taking place before lawmakers departed Washington.
The House is scheduled to return following the November midterm elections, meaning the impeachment battle could resume when lawmakers reconvene.
Whether Massie's effort ultimately receives enough support to advance remains unresolved.
What is already established, however, is an extraordinary break within the Republican Party: a Republican member of Congress has formally accused the Republican administration's defense secretary of committing impeachable offenses and placed eight separate charges against him before the House of Representatives.
