Edit: He said on Morning Joe that Trump Sr was not part of this conversation and his head would be rolling for suggesting such a deal. What makes you think this is Trump Sr's style? From what I can see from his campaign he is very hard working. Always willing to give media reports and has very rapid response times. He responded to Nice within 8 minutes.
If anything hiring someone else to do the job seems to be Hillary's style. She always has surrogates speaking to the media. Trump isn't afraid of defending his position to highly critical media. Its something that even his critics admire.
No matter if you are a Trump support or hate. There are definitely things you can admire about Trump's character.
