**Kristi Noem served as U.S. Secretary of Homeland Security from January 2025 until her removal by President Trump in March 2026.** In mid-January 2026, House Democrats led by Rep. Robin Kelly introduced articles of impeachment (H.Res. 996) alleging obstruction of Congress, violations of public trust tied to immigration enforcement incidents, and self-dealing. The resolution attracted over 140 Democratic co-sponsors but was referred to the Republican-controlled House Judiciary Committee, where it stalled without bipartisan support or floor action. Republican majorities in both chambers made conviction and removal in the Senate improbable, as a two-thirds vote would have been required. Trump’s decision to replace Noem with Sen. Markwayne Mullin and reassign her to the newly created role of Special Envoy for the Shield of the Americas effectively ended her tenure in the impeachable cabinet position by late March. No subsequent legislative efforts or procedural advances have materialized through September 2026. Trader consensus at 97.5% against impeachment reflects these institutional barriers and the absence of cross-aisle momentum. Realistic scenarios that could still alter the outcome before year-end include a Democratic House takeover after the November 2026 midterms enabling renewed proceedings against her in any remaining federal capacity, or the emergence of new, high-impact allegations prompting unexpected Republican defections—though both remain low-probability given the timeline and current alignment.
