One of the most emotional moments in the four-day convention came from Khizr Khan, the father of a Muslim US soldier killed in Iraq.

His steely admonishment of Clinton's Republican adversary Donald Trump at once electrified the convention and brought many to tears.

"Hillary Clinton was right when said my son was the best of America. If it was up to Donald Trump, he never would have been in America," Khan said, describing his family as "patriotic American Muslims."

"Donald Trump, you are asking Americans to trust you with their future, let me ask you -- have you even read the United States Constitution?" he said, brandishing a copy.

"I will gladly lend you my copy!" Khan said, insisting Trump look for the word "liberty" and consult the 14th amendment, which guarantees equal protection before the law.

"Have you ever been to Arlington cemetery?" he demanded. "Go look at the graves of brave patriots who died defending the United States of America. You will see all faiths, genders and ethnicities."

"You have sacrificed nothing, and no one!" he said.
