New officialMarkwayne Mullin is new on Open Cabinet. We added 89 trades from a 278-T posted to OGE on July 25, 2026 (added July 25, 2026). Officials have 30 to 45 days to report each trade, so transaction dates can be earlier than the filing date.
MMMarkwayne Mullin
Secretary · Department of Homeland Security
Mullin reported 89 sales and no purchases across 89 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 89 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.
Every transaction on file is a sale. 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.
