Republican lawmaker files impeachment resolution against Pentagon chief

US Defense Secretary Pete Hegseth faces an impeachment resolution filed Monday by Republican Congressman Thomas Massie, who accuses him of waging war against Iran without congressional approval. A House vote could occur this week. Massie alleges Hegseth demonstrated he remains a constitutional threat through conduct incompatible with the rule of law. The resolution may pass the Republican-controlled House before Democrats take over January 3, though Senate conviction is unlikely given the two-thirds majority requirement. House Speaker Mike Johnson opposes the effort, citing ongoing overseas hostilities. Hegseth vows to fight the charges, comparing himself to President Trump, who survived two impeachments. Trump has publicly supported Hegseth.
