Well, unfortunately(?) the organization you call a ‘grifter’ gave me my opportunity to hear my President tonight.
(Maybe you should talk to Trump about the organizations from whom he accepts invitations to speak. I don’t make his decisions, I’m just always glad to see him.)
Of course they're going to give Trump the stage because he's the leader of the very base that they need to snooker for donations and pledges every 2-4 years.
