She must have some incriminating info. to have been blocked from testifying. I think the leftist-radicals are afraid a woman testifying might get the attention of Obama's base; The 20-something bimbo female.
Victoria Toensing is the attorney representing the 4th witness. The article says the witness may be “he or she” so we don’t know whether the 4th witness is a woman or man. Whoever it may be, we need to get through the administration’s crap red tape to have the testimony given publicly asap.
Obviously, this will help clear Hillary's name, Susan Rice, and the Obama Administration quickly... (only if they are innocent...)
