Wave of Expulsions Threatens Capitol Hill Stability

US Capitol Building against blue sky.

Expulsions from the US House remain extraordinarily rare, with only six in history, yet whispers of a new wave tied to misconduct threaten to shatter Capitol Hill’s fragile stability ahead of 2026 midterms.

Story Snapshot

  • House expulsions total just six since 1789, mostly Civil War era or criminal convictions.
  • Recent buzz centers on Reps. Eric Swalwell and Marjorie Taylor Greene amid misconduct claims and party breaks.
  • Republicans defend razor-thin majority as retirements and potential ousters reshape power balance.
  • Democrats eye competitive districts for gains in high-stakes 2026 midterms.
  • Voluntary exits by Pelosi and others signal deeper political churn, not formal expulsions.

Historical Rarity of House Expulsions

House members face expulsion only through a two-thirds vote, a threshold met six times since 1789. Civil War disloyalty accounted for most in 1861. Post-war, James Traficant exited in 2002 after 420-1 vote for corruption. George Santos became the sixth in 2023 following ethics probes on campaign fund misuse. These cases demand overwhelming bipartisan support, underscoring expulsion’s gravity as ultimate accountability.

Current Wave of Departures Reshapes Congress

Former Speaker Nancy Pelosi retires after 40 years. Rep. Marjorie Taylor Greene resigns amid public rift with Trump. Rep. Lloyd Doggett bows out due to Supreme Court-upheld redistricting. Rep. Jared Golden cites rising threats and incivility. These voluntary moves hit Republicans hardest, complicating their slim majority defense. Democrats spot openings in battleground seats.

Key Players Facing Scrutiny and Exit

Rep. Eric Swalwell denies sexual misconduct allegations fueling expulsion talks. Rep. Troy Nehls, Jodey Arrington, and Andy Biggs depart amid party pressures. Reps. Nydia Velázquez, Bonnie Watson Coleman, Chuy García eye retirement. Nancy Mace, Byron Donalds, Chip Roy, Barry Moore, Buddy Carter pursue higher ambitions. High-profile exits like Sen. Joni Ernst’s non-reelection scramble Iowa races, with Rep. Ashley Hinson and Randy Feenstra jumping in.

Republican Majority Hangs by Thread

Each vacancy endangers GOP control in a narrowly held House. Trump’s staunch allies among leavers amplify risks. Common sense dictates strategic positioning drives many decisions—pursuing governorships or Senate bids over tough reelections. Facts align with conservative values: accountability for misconduct strengthens institutions, but partisan witch hunts erode trust. Retirements barometer political winds, per expert views.

2026 Midterms Face Unpredictable Map

Short-term, real-time redraws favor Democrats in open competitive districts. Long-term, this churn sets explosive midterm battles. Broader trends show ambition shifting toward statehouses and Senate. Limited expulsion specifics highlight voluntary departures dominate, not formal ousters. House braces for turbulence as power tilts precariously.
