Trump has shown other examples of shooting the messenger without listening to the message. He condemned the public plea for help by the mayor of San Juan, Puerto Rico. He wasn’t concerned with the contents of the White House leaks, but wanted to punish the leakers.
People are using any platform that is most readily available to them. As a marketing expert, Trump should know this. This is why many brands use recognizable names and faces to sponsor products. Trump may not agree with how the message was sent, but it would help if he would acknowledge the message was delivered and heard.
