PHILADELPHIA — The Muslim-immigrant father of a U.S. Army captain

killed in the Iraq War lashed out at Donald Trump, saying: "You have sacrificed nothing and no one" for the U.S.

Holding a Constitution while speaking on the final night of the Democratic National Convention, Khizr Khan told the audience that "Donald Trump consistently smears the character of Muslims."

"He disrespects other minorities, women, judges, even his own party leadership. He vows to build walls and ban us from this country. Donald Trump, you are asking Americans to trust you with our future. Let me ask you: Have you even read the U.S. Constitution? I will gladly lend you my copy."
