If  you consider the true contexts to be of relevant importance then one needs to be aware that Army Capt. Humayun Khan, 27, died from a suicide bombing in Baghdad 12 years ago [2004?]. Trump didn't say anything back in 2004 or prior to my knowledge? Did Trump direct his thoughts on Muslim immigration naming in particular  Army Capt. Humayun Khan at anytime? Seems to me some other motivation's perhaps [political] brought his family to the DNC stage 12 years after the unrelated tragic killing of  Army Capt. Humayun Khan.
