Nah, I don’t believe Trump is behind it, he warned him that he might spill the beans, but that is it.
This goes much higher in the Political Food Chain.
The GOPe, and SuperPACs and factions of the Democratic Party desperate to not lose power, are doing everything to discredit both Candidates, put in their own candidate that is a plant that Hillary can easily defeat.
Both have to come together, and put this to rest immediately, or both might lose.
A brokered convention where delegates can pick who they want is the bleak forcast if one of them does not reach 1237
Trump tweeted (for a short moment before retracting) that he might spill the beans on Cruz's wife. I took that to mean he had knowledge on some financial/political scandal. The NE piece has nothing to do with Cruz's wife except that she is the hurt party (whether the story is true or not).
