Well, I think there is. I think it's unusual in this environment to rebuff Trump. I also think it's unusual that Kemp not explain his pick. It's certainly not required, but it is unusual in this razor-thin majority, fight to death environment.
I wish Kemp would explain his reasons. He hasn't done so to my knowledge. Financing would be a valid reason - hell, any reason would be helpful to all three of them.
I'm sure the rationale for his appointment has been given to President Trump.
