So the Chief of Staff is going to get treated the same way as the VP as it relates to meeting with foreign countries and wielding influence internationally?
Will Newt if Chief of Staff unintentionally upstage whoever the VP is at any meeting? Newt is of the caliber, not by his own ego, but strictly by his intelligence and experience that people will want to know his opinion and insight on every matter. That kind of insight deserves the respect of being nominated as VP.
The role of Chief of Staff is that of a mover and a shaker. Where POTUS goes, the COS goes. The COS will be in far more meetings with foreign leaders than the VP will. And, remember, NO ONE sees POTUS without going through the COS.
