The ones whose wealth suddenly exceeded their salaries.
Legislation was passed in 2012 under Obama...................there was a provision where you could track congressional stock transactions on line.............it was very popular. It caused all kinds of problems for congress at the time. Paul Ryan was speaker then. I forget exactly when it was, but the law was changed from online access and instead, sent to the archives or library, I forget, and if you wanted to look into stock trades, you had to do so in person and physically look it up yourself. It was one of the last actions of that number congress with Ryan at the helm.
