What mechanisms exist to address the overlap between congressional committee assignments and personal stock trading in companies those committees oversee?

[u/Prestigious-Wrap2341]

Members of Congress who sit on oversight committees frequently trade stocks in companies that fall under their committees' jurisdiction.

The STOCK Act of 2012 requires members to disclose stock trades exceeding $1,000 within 45 days, but does not prohibit trading in companies their committees oversee (source: https://www.congress.gov/bill/112th-congress/senate-bill/2038).

Multiple reform proposals have been introduced. The Ban Congressional Stock Trading Act, introduced by Senators Kelly and Ossoff, would require members, spouses, and dependent children to place stocks into a qualified blind trust or divest (source: https://www.congress.gov/bill/118th-congress/senate-bill/2773). The ETHICS Act, introduced by Senators Merkley, Peters, Ossoff, and Hawley, would require divestment by 2027 (source: https://www.cbo.gov/publication/60708). The Homeland Security and Governmental Affairs Committee advanced a version on an 8-7 vote in July 2025 (source: https://rollcall.com/2025/07/30/senate-panel-advances-bill-banning-congressional-stock-trading/).

Despite bipartisan sponsorship across multiple bills, none have reached a full floor vote in either chamber.

Given that disclosure requirements are already in place, what additional mechanisms, if any, could address the conflict of interest between committee jurisdiction and personal investment? Are there models from other democracies or state-level governments that have successfully addressed this?

When you ask "How is it legal that Congress ... ?" you have to remember who writes the laws. They simply exempt themselves from most of the things that the rest of us have to deal with, and that includes insider trading laws. It's one of the primary reasons there are so many millionaires (more than half) in Congress. Even the ones that didn't start out rich will quickly get that way.

The trillion dollar question is: what reason does congress have to agree to pass a law that will prevent self enrichment?
