Where is that right enumerated?
____________________________________________________________
The Constitutional requirements for Presidential eligibility is the law to be enforced (where it is enumerated in your language).
The Constitution requires the President to be a natural-born citizen, over 35, and for 14 years a resident of the country. It is silent on how those qualifications must be proven and who to. Nor is there any law laying out how the President needs to prove he's constitutionally eligible. The requirement to be eligible is there. But this right you claim requires him to prove it to you doesn't exist.
