In April 2023, Texas Republican Representative Michael McCaul led an official visit by U.S. lawmakers to Taiwan, meeting with senior officials and business leaders to discuss ways to strengthen the “economic and defense relationship” between the two countries. The same year, McCaul’s wife purchased stock, valued at up to $250,000, in the Taiwan Semiconductor Manufacturing Company, while he chaired the House Committee on Foreign Affairs. His family continued trading in TSMC stock for the rest of his tenure as chair, even as he led a second official trip to Taiwan in May 2024.
Stock trading by U.S. lawmakers, despite being legal, has been a controversial subject in American politics for years. Members of Congress serve on committees that grant them access to privileged information on matters of national security, technology, and foreign affairs, among other subjects. There have long been concerns about lawmakers using this nonpublic information to trade individual stocks or engage in insider trading, and several bills to ban the practice have bipartisan support. Former House Speaker Nancy Pelosi is cited as one of the most prominent examples by critics, including President Donald Trump, especially since her husband’s portfolio generated cumulative returns of 838% over the past decade. Pelosi insists the claims are “ridiculous” and that she is not involved in her spouse’s trading activities.
