Rep. David J. Taylor, a member of the U.S. House of Representatives, has disclosed the sale of Marathon Petroleum Corporation (NYSE: MPC) common stock in a Periodic Transaction Report filed under the STOCK Act. The transaction, dated July 24, 2026, was valued between $1,001 and $15,000, according to the disclosure.
The filing lists the sale as made by Taylor himself, held through the David Taylor Trust via a Schwab Joint Brokerage account internally labeled ‘Home Grown.’ STOCK Act rules require members of Congress and their families to report trades like this one within 45 days, giving the public a window into how lawmakers manage their personal investments while serving in office. Filing a disclosure like this is a legal obligation, not an indication of any wrongdoing.
A Notable Timing Overlap
What makes this filing worth flagging is its proximity to another sale of the same stock. Company insider Mannen Maryann T. also sold shares of Marathon Petroleum, offloading $283,096 worth of MPC stock on August 3, 2026 — within 30 days of Taylor’s reported transaction. Whoisbuyingnow.com tracks these kinds of overlapping signals because they can indicate broader sentiment shifts around a company, even when the individuals involved have no connection to one another and no evidence suggests coordination.
Congressional trades and corporate insider trades are reported through entirely separate systems — the STOCK Act for lawmakers and SEC Form 4 filings for company insiders — so seeing both types of sales cluster around the same window is simply a pattern worth noting, not a claim of any relationship between the two parties.
Why This Gets Tracked
Interest in monitoring how members of Congress trade stocks has grown steadily, with readers increasingly searching for ways to track senator and representative stock trades as they’re filed. Tools and trackers built around STOCK Act disclosures exist precisely because these filings are public but scattered across House and Senate databases, making it hard to spot patterns like the one seen here without aggregating the data.
Marathon Petroleum has seen multiple insider and congressional filings this year, and this latest disclosure adds another data point to that record. As with all STOCK Act filings, the report reflects a required disclosure of a completed transaction, not a recommendation or signal to act on. Whoisbuyingnow.com will continue monitoring for additional filings tied to MPC and to Rep. Taylor’s broader trading history as they become available.
