Why Two Oaths of Office for President?

Another point of interest Winston notes in that May 04, 2012 David Wilcock interview: The 1788-89 Constitution Article II Oath of Office has always been used by the U.S. elected presidents since the very beginning with the very 1st president of America - George Washington. This is in regard to the particular Oath of Office that he chose to make his allegiance to. As opposed to the Article VI Oath of Office, Winston explains: the Article II Oath is for employees.

Dr. Eduardo M. Rivera, Professor of Law & Government also agrees:

“[George] Washington took an oath of personal employment to "preserve, protect and defend the Constitution of the United States," for a government employer. Washington could have taken the Article VI Oath specifically provided for "all executive and judicial Officers, both of the United States and of the several States." Instead, Washington set the secret precedent that he and future Presidents would work for the Congress of the United States as its employees.

Washington’s agreement to work for Congress amounted to a false oath, because everyone not intimate with members of the First Congress and George Washington believed that the oath would bind George Washington "to support this Constitution." That mistaken belief that "this Constitution" had been adopted enslaved millions of Americans to a Constitution of no authority. [/u][/b]”

Note: The significant verbiage to be noted is pointed out by Dr Eduardo M. Rivera. Specifically, the Article II Oath of Office (taken by every president since the time of Washington) lacks the notion that the president is sworn to "support" the Constitution.

On the contrary, the Article VI Oath says:

"I, [name], do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. [So help me God.]"

So, this adds more support to this notion that Paul Ryan is positioned as an "interim president" for the upcoming establishment of a Republic form government, as he has taken the Article VI Oath of Office - in support of the Constitution, rather than taking the Article II Oath of Office to act as just another 'employee' of the de facto corporate government.

Just have to keep watching this to see if this will actually unfold.
