Rep. Eric Swalwell (D-CA) announced stepping down yesterday, citing allegations (which he calls false) as a distraction from his work—he's also running for California governor.
Rep. Tony Gonzales (R-TX) is retiring after admitting an extramarital affair with a former staffer who died by suicide last Sept; he's facing a House Ethics probe, and GOP leaders urged him not to seek reelection.
These fit a broader 2026 trend: 57+ House members (mostly Republicans) not running again due to gridlock, family, or other pursuits.
