Merck & Co. (Health Care) appears in federal disclosure records across 31 members of Congress, who collectively reported 107 trades between July 2020 and June 2026, with the balance nearly even at 52 purchases against 55 sales, reflecting a marginal net-selling posture over that span. Among the most active disclosing members by trade count are Ro Khanna, Michael McCaul, Gil Cisneros, and Jared Moskowitz, and the record shows four bipartisan co-trading clusters, indicating the name drew disclosed activity from members across party lines. In the executive branch, 32 officials separately disclosed 55 transactions in the same security, with the closest congressional and executive purchases falling zero days apart in the public filing sequence — an overlap observed in independent disclosures. Merck is a widely held large-cap Health Care name, and the breadth and bipartisan character of its congressional trading record is consistent with that profile.
