Washington (AFP) — Two United States lawmakers stepped down Monday and two more faced possible expulsion over a series of scandals that have rattled both parties and thrown the House of Representatives into turmoil.

Democrat Eric Swalwell of California, who had already ended his bid to become governor, announced his resignation from Congress on Monday via X, after multiple women accused him of sexual assault or misconduct.

Hours later, Texas Republican Tony Gonzales announced plans to retire from office in an X post, amid mounting pressure after acknowledging an affair with a former aide who later died by self-immolation. House Speaker Mike Johnson and other Republican leaders had already urged him not to seek reelection.

Lawmakers are still zeroing in on separate controversies involving two Florida lawmakers — Democrat Sheila Cherfilus-McCormick and Republican Cory Mills — in an unusual push for disciplinary action.

“Congress should not tolerate representatives who abuse staff, betray public trust for personal gain, and generally violate their oath of office,” New York Democrat Nydia Velazquez posted on X, calling for all four to resign and adding “if they refuse, they should be expelled.”

Expulsion from the House requires a two-thirds majority, a threshold so high that Congress has wielded the sanction only in the gravest cases, removing just six members in its 237-year history.
