You asked whether or not he was ever asked. Did you find an instance where he was asked? If not, the reason you probably can’t find a denial is because no one ever asked him about it - probably because the source for this rumor is not credible to begin with.
I know what I asked, but once again, I can’t find anything on him commenting if he had or did not have prior knowledge of this armed commando style raid on Trumps private residence.
Maybe I am missing it. Do you have information from him on this?
