I think that if this is nothing to be concerned about, it is because people have not gotten to the bottom of it.
Were it not for a former aide disclosing this, the public would not know about it. If that is all right with you, then we should get rid of the Senate disclosure rules all together, since people who think like you do not apparently want to know of the secretive dealing of their Senators, including those who are keeping matters secret because they have relatives on local commissions who can act in the Senator's interest without anyone knowing about it.
The issue to me is the non-disclosure, and if it turned out to be legit, then why did he hide this? Why did his high-powered lawyer not follow the rules? They had to know that it would come out eventually...that is unless of course they did not want anyone to know that he would profit from the sale while the man's son was involved.
Ethics is more than accounting...its about trust.
