Again the MSM is not telling the whole story.  Khizr Khan is a Muslim brotherhood agent that promotes Muslims coming into to the USA that support Sharia Law.  Khan is a Muslim and Muslims follow the Koran.  
The Koran contains numerous passages advocating violence against infidels and tells Muslims to main and kill those that criticize Islam.  Trump is right on in criticizing this religion and what it stands for.  The liberals like Hillary Clinton are like the Greeks welcoming the Trojan Horse.  Letting Khan speak at the DNC convention was insanity!  This shows how weak and stupid the Democrats are.
