The Salahis' excuse their cell phone battery was dead, as the reason for not getting the message that they were not invited. What sense of entitlment do these two things they have. Check their cell phone records, see what calls were placed to and for this cell phone prior to and after the message. They didn't want to be told "NO, you're not invited". So, they probabaly got the message, but denied receiving it. Are they that naive to believe their cell phone records cannot be used agasint them.
Conviict them, bar them from coming anywhere the President for the next 4 years, and strip them of all profits from this event.
Maybe even put them on the no-fly list for at least 12 months.
