MMMarkwayne Mullin
Secretary · Department of Homeland Security
Mullin reported 98 sales and no purchases across 98 transactions in 278-T filings tracked by Open Cabinet, all dated between April 15 and June 10, 2026 — the months after his March 24, 2026 confirmation as Secretary of Homeland Security. All 98 transactions were flagged as filed late. Both filings also carry an Integrity.gov notice that Mullin received a 45-day filing extension, so trades flagged late may have been reported within his extended deadline.

This total aggregates every source filing listed below. Public trackers focused on a single disclosure may report smaller counts for the same official.
The counted trades include sales and no purchases. This is the pattern you would expect from an official liquidating positions to comply with an ethics agreement, but Open Cabinet does not yet ingest the entry-disclosure baseline (Nominee 278) needed to confirm which holdings have been fully divested.
