For anyone who does not know or anyone who forgot, Donald Trump stated that he would not release his tax returns if President Obama did not release his long form birth certificate. Now someone should demand to see Trump's tax returns. In my opinion, this is a win-win situation. If Trump releases his tax returns people know his actual net worth. If he does not release his tax returns he loses even more credibility with the majority of the American people.
It does seem that Robert Gibbs is asking for Trump's tax returns. The second link is to an article on the CBS website in which Gibbs recalls Trump's comments about his tax returns and President Obama's birth certificate and asks for Trump's tax returns.
