Clinton web ad - Why is Trump not releasing his taxes UPDATE comments from person who has seen them

Enjoy

Politico story on the ad here

UPDATE listening to MS-NBC.  Man on who has seen taxes, cannot talk specifics.  Raised four areas Trump might not want people to see

1.  What his actual level of income is — implication that income, and hence wealth, much lower than he says

2.  His level of charitable giving.  Implication is that he is NOT claiming much for a wealthy person

3.  What percentage of income is coming from overseas entities

4.  To what financial/business interest pressure he could be subject to given financial support etc from overseas?

“I think the tax returns could raise a number of questions he does not want to answer.”
