Ban all stock trading by members of congress and their familys and political office holders. All stock assets to be frozen or sold before swearing in and cannot be touched while in office and a probationary time after, say 3 years. They are there to serve. Not make money.
Including this there should be bi-annual audits of all members to check for any (dirty) money including influxes from random sources, lobbying and favors.
This I believe would curtail the clear abuse of office happening now every day. Looking at you Nancy Pelosi.
We have got to get back to public servants that actually serve i stead of just lining their pockets
