Would I wrong to say that trump knew very well that this fire was going to happen, not only did he know this was going to happen he was hoping it would so certain people would then find something which then they used to raid his lawyer on purpose but knew also that this would lead to nothing against him, but in return then give say a problem for poor ol' RR. A reason to fire him without making it look like trump overstepped his authority? I think this is the case personally, he always seems a few steps ahead of those who wish to remove him but always acts like a bird with a broken wing before ending his opponent. If my thought is true then the future will prove this later on. Be cautious but trust the plan. As Q said, full control.
Now where is the fun in guessing if you are just going to go ahead and use Occam's razor and jump to the most likely and simple reason.
