Look NSA is not a law enforcement organization!!!!!!!!!!!!
Anyone who thinks that NSA CIA, DIA, ONI INR has anything to do with law enforcement watches to much TV !!!!!1
The only reason to pass a NSA background check is to work at or work with NSA.
The Constitution does NOT require any background checks for presidential eligibility. It sets the eligibility standard as natural born. Its the states (Remember those sovereign but now cowardly entities!) responsibility to determine ballot eligibility to be listed on the ballot.

The Constitution does NOT require any background checks for presidential eligibility

That is correct. But in order to have access to classified information, especially Sensitive Compartmented Information (SCI), a full Background investigation is required. Is this waived for the President? I honestly don't know.

And what about classified information designated as "NOFORN" (Not releasable to Foreign Nationals).

So could someone serve in the office of POTUS and not be allowed access to classified information? And could certain agencies of the US government unilaterally deny certain information to the POTUS because they (the agency) deems him to be untrustworthy?

Just throwing these questions out there.
