Democrats' decisive 2026 midterm gains, securing House and Senate majorities effective January 2027, have accelerated impeachment activity targeting Trump administration officials. Republican Representative Thomas Massie introduced articles against Defense Secretary Pete Hegseth over the Iran conflict and Pentagon oversight, with incoming House leadership signaling support for a floor vote as early as the lame-duck session. Traders price Hegseth highest for a House impeachment by June 30, 2027, reflecting bipartisan momentum and procedural rules allowing a simple majority. President Trump faces renewed scrutiny from multiple filed resolutions, though Senate conviction thresholds remain high; other cabinet nominees draw lower probabilities absent similar immediate catalysts. Resolution depends solely on House passage of articles, with scheduled legislative returns and committee actions serving as near-term indicators.
