First the concept of "kayfabe":
In professional wrestling, kayfabe is the portrayal of staged events within the industry as "real" or "true," specifically the portrayal of competition, rivalries, and relationships between participants as being genuine and not of a staged or pre-determined nature. Kayfabe has also evolved to become a code word of sorts for maintaining this "reality" within the realm of the general public. Though the general public had been aware of the staged nature of professional wrestling for decades, professional wrestling industry did not formally acknowledge this until 1989 when Vince McMahon testified before the New Jersey state senate that wrestling was staged, in order to avoid taxation on his in-house shows and pay-per-view events.
Then suspicions of kayfabe in the feud between Fox and Trump:

It would not surprise me in the least bit to find out that Vince McMahon is one of Trump's campaign advisers.
