Law of nations (See: US Const. Art 1 Sect 8 P 10) referred by framers also defined "natural born citizen" (Law of Nations: Book 1 Ch 19 Sect 212) of being the second-generation born of two citizens (parents) of country (USA). By admission of Barack Hussein Obama (Soetoro) Jr, neither father nor adoptive father were US Citizens at time of birth or adoption, therefore this disqualifies B. Obama under US Const. Art 2 Sect 1 P 5 of being "natural born" as not at least a second-generation citizen of United States.
As being ineligible to hold the office of the President of the United States all acts, executive orders, etc. whilst in that capacity are null and void.
Wherefore, your resignation and departure from this high office is required forthwith.
