Notice how we keep getting the question about whether the President's staff has ever issued a statement. It is meant to imply that they have no rebuttal, and therefore this article is true.
If I remember correctly, this whole canard is due to missing records from the National Guard, which given that they happened almost 30 years ago is not unusual. My father's WWII records are also missing, but I still believe he served (and have the medals to prove it).
New tactic by the left: show up asking for information to refute a scandalous charge. Bah!
