- Taylor sits on the Subcommittee on Railroads, Pipelines, and Hazardous Materials, which oversees the regulator (PHMSA) that handles Marathon's safety permits.

Rep. David J. Taylor (R-OH), a freshman lawmaker, recently disclosed a sale of Marathon Petroleum Corporation (MPC) stock. The transaction, valued between $1,001 and $15,000, occurred on September 22, 2026, and was disclosed just nine days later on October 1.
Taylor sits on the House Committee on Transportation and Infrastructure, specifically serving on the Subcommittee on Railroads, Pipelines, and Hazardous Materials. This subcommittee holds direct legislative and oversight jurisdiction over the Pipeline and Hazardous Materials Safety Administration (PHMSA)—the federal regulator overseeing pipeline safety and hazardous materials transport. Just weeks prior to the trade, on August 6, PHMSA published a notice listing Marathon Petroleum Company LP as an applicant for a special permit regarding pipeline pigging operations.
While the overlap between a regulator's duties and their personal portfolio is notable, Taylor's trading activity on September 22 suggests a routine financial motivation. On the exact same day, Taylor executed two purchases of similar size, buying shares in Home Depot and Amgen, each in the same $1,001 to $15,000 range. Our analysis scored the trade 34/100, indicating that the transaction was likely a routine portfolio rebalancing to fund those new acquisitions.
This transaction marks Taylor's fifth sale of Marathon stock, continuing a systematic pattern of trimming his position. He was not the only one selling; corporate insiders at Marathon, including Senior Vice President Shawn M. Lyon, also lightened their holdings in late August. The sales followed a strong second-quarter earnings report in early August. Since Taylor's transaction, Marathon's stock price has risen by approximately 11.4%.
Members of Congress are required by the STOCK Act to disclose trades within 45 days, and disclosed amounts are reported in ranges.
For now, Taylor’s pipeline to the energy sector is running just a little lighter.
