U.S. House Agriculture and Science Committee Member Buys Defense and Exchange Stocks Simultaneously, Raising Conflict of Interest Concerns

April McClain Delaney, a Democratic member of the U.S. House of Representatives, disclosed on April 6 that she purchased shares in individual aerospace defense manufacturers and U.S. stock-exchange operators during April. According to her disclosure, the largest positions were in TransDigm Group Incorporated (TDG), a supplier of high-value parts for commercial and military aircraft, and Nasdaq, Inc. (NDAQ), the operator of the Nasdaq stock exchange. Under congressional trading limits, her single‐transaction caps for these two names were set at $50,000 and $15,000, respectively (approximately ₩70 million and ₩21 million). She also made smaller purchases in semiconductor materials, insurance, packaging, and medical-equipment stocks.

TransDigm Group is known as a midsize aerospace and defense company that has grown largely through mergers and acquisitions, supplying mission-critical components to airlines and defense contractors. On April 16—the date of Delaney’s first purchase—TDG shares fell 3.64% to close at $1,228.23. By the end of April, the stock had slid into the $1,140 range. After reporting strong second-quarter results and announcing financing plans for its acquisition of Stellant Systems, TDG recovered to $1,215.08 on May 8, but it remains about 25% below its 52-week high. The company has faced congressional and Pentagon audits in the past over allegations of excessive profits on defense spare-parts contracts, and legislators’ direct investments in defense firms have fueled ongoing conflict-of-interest debates—an issue likely to draw scrutiny given Delaney’s seat on the House Science, Space, and Technology Committee.

Nasdaq, Inc., headquartered in New York, operates the world’s second-largest equities and derivatives exchange and provides market data and fintech solutions. In its first quarter of fiscal 2026, Nasdaq reported net revenues up 14% year-over-year and non-GAAP diluted EPS rising 22%, marking double-digit growth across all business segments. On April 24—the day Delaney bought Nasdaq shares—the stock climbed 3.29% to $89.90. After several trading swings, it stood at $88.91 on May 8, about 12% below its 52-week peak of $101.79. As an exchange operator, Nasdaq’s performance is highly sensitive to regulatory developments, interest-rate moves, and trading-volume cycles, and it may be directly affected by future market-structure reforms or digital-asset regulation.

Delaney represents Maryland’s 6th Congressional District as a freshman member. She serves on both the House Agriculture Committee and the Science, Space, and Technology Committee, where she participates in subcommittees on commodities, digital assets, and rural development. Her “Costs Down, Opportunity Up” agenda, aimed at easing household expenses and ensuring fair corporate contributions, along with her bipartisan broadband legislation to expand high-speed internet in rural areas, have been central to her platform. Nonetheless, her personal holdings in a defense contractor and a major exchange operator—while sitting on committees that oversee defense budgets, federal research and development, and commodity and digital-asset markets—may raise questions of overlapping policy influence and investment interests. Even though she complied with STOCK Act disclosure requirements, critics may argue that the trades pose regulatory risk and invite public criticism. As Congress continues to debate a potential outright ban on members’ stock trading, this latest disclosure could renew calls for stronger conflict-of-interest safeguards, such as mandatory blind trusts.
