WASHINGTON — Republican U.S. Representative Thomas Massie has filed articles of impeachment against Defense Secretary Pete Hegseth, accusing him of abusing his office in connection with U.S. military operations against Iran.
The move marks a significant political challenge from within President Donald Trump’s own Republican Party as debate intensifies in Washington over the ongoing Iran conflict and Congress’ constitutional role in authorizing military action.
Massie Challenges Iran War Authority
Massie, a Republican from Kentucky and an outspoken critic of the Iran war, argues that Hegseth carried out military hostilities against Iran without the required authorization from Congress.
The impeachment resolution was introduced as a privileged measure, meaning the House of Representatives must address it within two legislative days.
The resolution faces long odds of ultimately succeeding, but it could still force lawmakers to publicly take a position on Hegseth and the administration’s handling of the Iran conflict.
Pentagon Defends Hegseth
The Pentagon pushed back against the impeachment effort and publicly defended the defense secretary.
Pentagon Press Secretary Kingsley Wilson said the department remains united behind Hegseth and would continue focusing on American service members and national interests.
Iran War Becoming a Major Political Issue
The confrontation comes at a sensitive moment for Washington.
The U.S.–Iran war, which began with U.S. and Israeli strikes against Iran on February 28, has become increasingly controversial as the conflict continues.
Members of Congress have repeatedly debated whether President Trump should be required to obtain congressional authorization to continue hostilities.
The political stakes are particularly high with the November 3 midterm elections approaching.
A recent Reuters/Ipsos poll showed Democrats leading Republicans 44% to 37% when Americans were asked which party they would support in congressional elections.
Economic Pressure Is Growing
The political dispute also comes as the financial consequences of the Iran conflict become clearer.
A new Congressional Budget Office assessment estimates that the war has already cost the United States approximately $38 billion, with costs potentially increasing by billions of dollars each month if operations continue.
Disruptions to Middle Eastern oil shipments have also contributed to higher energy prices, increasing pressure on American households.
Massie’s impeachment push is unlikely to remove Hegseth from office, but it could force another major congressional confrontation over the Iran war — and put Republican lawmakers on the record just weeks before voters head to the polls.
