From _BRUCE BARTLETT_ (mailto:bartlettb@cox.net) :
Having worked in the White House, I can assure everyone that not only would it be impossible to get a White House pass using an alias, it is impossible even to get past the gate for an appointment using an alias. Thorough FBI background checks are required for the former and a picture ID is necessary for the latter. Therefore, if Gannon was using an alias, White House staff had to be involved in maintaining his cover.
