To be perfectly honest, isn't it high time that there be a general requirement that all significant investments by a member of Congress be held in a blind trust during the member's term?
No ifs, and, or buts. If you are elected to Congress, all of your pre-existing investments must be handled by a blind trust, and you can contribute as much new money to the blind trust as you like, but that money is then invested by the trustee of the blind trust.
