Trump’s second-term administration has seen record turnover among political appointees and Senate-confirmed officials, with more than 900 non-confirmed roles vacated in the first 18 months—far exceeding prior administrations. Key 2026 departures include firings of DHS Secretary Kristi Noem over immigration enforcement and disaster response criticism, Attorney General Pam Bondi amid Epstein files handling disputes, and resignations by Labor Secretary Lori Chavez-DeRemer, DNI Tulsi Gabbard for family health reasons, and White House Press Secretary Karoline Leavitt for personal priorities. Additional exits have hit Treasury, White House staff, and agencies amid private-sector moves, internal friction, and performance expectations. Ongoing pressures from policy execution, midterms, and loyalty standards continue to shape departure risks through year-end.
