1 Section 1: President and Vice President
There are several 'Section' that should be looked into but he oath of office seems to me to be the one that is over looked the most especially with our current situation in the White House. Let's take a look at the oath of affirmation. Clause 8 Before he enters the Execution of his Office, he shall take the following Oath or Affirmation:—"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."
2.1 Clause 1: Command of military; Opinions of cabinet secretaries; Pardons
2.2 Clause 2: Advice and Consent Clause
2.3 Clause 3: Recess appointments
Once again keep these Powers to in mind. Let's take a look at what relinquishes the power of the military from the president. The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.
