The primary and unwaivable requirement for a CIA agent is unquestionable loyalty to the Constitution of the United States. A Farrakhan Muslim is very unlikely to put the interests of the US before the interests of Muslims, and most of them are likely to have criminal inclinations (as demonstrated here)
Well I guess the CIA screwed up then. This guy is more loyal to his Johnson than to the United States.
If the CIA is all that loyal to the Constitution they will have one hell of a job working for this unConstitutional President we have now.
