Prohibit all Members of congress from trading stocks or bonds while they are in office. Congress should not be allowed to profit off of their votes or profit off of insider information. They must put all portfolios in an untouchable lockbox during their tenure. This will return trust to the American people.
As the President cannot trade qhile in office, nor shall any member of congress be able to trade as well. Prohibit any member of congress of opening any new accounts, lock down all family account as well so the policy cannot be circumvented.
