Yes, Wilson is virulently anti-Trump but I doubt Rubio and Cruz are involved with this. Rubio, in particular, does not want to get down and dirty with Trump’s people given what’s out there on him.
Don’t be surprised if this original fake news is traced back to the
campaign of of one of Trumps primary opponents. It obviously was not
leaked during the primaries, but that does not mean it did not originate
with one of the primary campaigns.
Time will tell.
