Like I say I don't know.

There was certainly CIA activity against Maduro, has been for a very long time. The CIA through thousands of organisations pays big bucks to officials to commit fraud, and to people on the street to protest and claim what they want claimed.  The CIA is extremely good at these kinds of things and very well funded.  So that is the other possibility, which is enough of a possibility that I don't even know which story is more likely at this point.
