Dad of Fallen Muslim Soldier Asks Trump: Want to Borrow My Copy of the American Constitution?

'You have sacrificed nothing and no one,' Khizr Khan told Trump at the DNC.

One of the most powerful and poignant moments of the Democratic National Convention’s four days came Thursday as the Muslim father of a slain American soldier blasted Donald Trump saying.

"You have sacrificed nothing and no one,” said Khizr Khan, who lost his son, 27-year-old Army Captain Humayun Khan, in a 2004 suicide blast in Iraq. 

Joined by his wife Ghazala, Khan spoke from the podium at Philadelphia’s Wells Fargo Center, taking Trump to task as he addressed the GOP candidate's stance on banning Muslims from the U.S.

"Donald Trump, you're asking Americans to trust you with their future. Let me ask you, have you even read the United States Constitution?" he said. "I will gladly lend you my copy. In this document, look for the words; look for the words, liberty and equal protection of law."

The proud father then pulled a copy of the Constitution from his jacket pocket and raised it in the air.

The Khans, who live in Charlottesville, Virginia, emigrated from the United Arab Emirates to Boston in 1980 when their son was 2. Humayun enrolled in the ROTC program while a student at University of Virginia where he graduated with a psychology degree before being deployed to Iraq.

Khan also slammed Trump’s immigration proposals, saying: "If it was up to Donald Trump, he never would have been in America. 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."

While Ghazala remained silent as her husband spoke, the look of anguish on the mother's face resonated with the audience.

"Have you ever been to Arlington Cemetery? Go look at the graves of the brave patriots who died defending America -- you will see all faiths, genders and ethnicities," the late soldier's father asked Trump Thursday during his speech.

Captain Khan was doing a routine check at the gates of an Army gate in Baqubah, Iraq, in June 2004 when a car rigged with explosives approached and detonated.

The captain, who signaled for the vehicle to stop and ordered other soldiers nearby to stay back, is credited with saving the lives of his comrades around the camp.

Captain Khan was posthumously awarded the Bronze Star and Purple Heart.
