Trump needs a quick response team. The way I would
respond would be to point out that Captain Kahn was
killed in 2004. Events SINCE that time make consideration
of the reevaluation of Muslim immigration a worthy
topic of discussion.
Or he could have said, if I had been President in 2004, the Captain Kahn would still be alive, or his son could have said that. Wait! Eric Trump did say that! WOW! That really shut the media up!
