I can't help but notice that Khan attacked Trump, not the other way around. And if we are to take Khan's criticism of Trump seriously (that Trump's family has never sacrificed), then we must ask why he doesn't criticize Clinton for exactly the same thing? The Clinton crime family not only has never sacrificed, but they hold the military in contempt and do not care a whit about protecting those who stand in harm's way. Four men died in Benghazi because of the Clinton contempt. And the Middle East is a cesspool because of liberal policies and actions.
Also, has Mrs. Khan been allowed to speak other than for a photo-op?
