I'm pretty sure she has a company do that for her. It doesn't stop the collusion, even if they were banned. I read somewhere most of the insider trading happens on the lower levels of companies and banks, because executives and other people are very closely monitored as well as their family.

Some have to divest completely like government officials, some have to make their trades public, but I don't think that applies to lawyers/judges, and definitely not everyone that in theory has insider information. You can go find and copy the portfolio of most powerful people.

I think government /executives shouldnt be allowed at all even through a company other than savings/retirement, judges and other position of influence (banks) should divest, and stocks should be left to the people. That's never going to happen
