**Republican Rep. Thomas Massie introduced privileged articles of impeachment against Defense Secretary Pete Hegseth on September 15, 2026, citing violations of the War Powers Resolution, unauthorized hostilities in Iran, civilian casualties, and related actions in other theaters.** Speaker Mike Johnson adjourned the House early to avoid a pre-midterm vote, pushing consideration into the lame-duck session beginning November 9. Earlier Democratic articles from April 2026 focused on similar unauthorized war claims and alleged misconduct. Hegseth’s Pentagon reforms, including senior officer removals and operational shifts amid the ongoing Iran conflict, have drawn bipartisan congressional criticism, though President Trump continues to support him. The timing of any House vote and Senate conviction threshold remain central variables for traders.
