In recent years, U.S. Congress members have been embroiled in controversy for using insider information for stock trading, leading to strong public dissatisfaction. In December 2024, President Biden publicly called for a ban on Congress members trading stocks while in office, emphasizing that legislators should not use their power for personal gain. Previously, bipartisan lawmakers have proposed related bills multiple times, attempting to prohibit members of Congress and their relatives from holding or trading individual stocks, with violators facing hefty fines. However, due to slow legislative progress and loose regulation, such proposals have not yet been fully implemented. Public opinion generally holds that restricting stock trading by lawmakers helps reduce conflicts of interest and restore public trust in the government.
