Khizr Khan, father of deceased Muslim US Soldier Humayun S. M. Khan, delivers remarks on the fourth day of the Democratic National Convention, July 28, 2016 in Philadelphia, Pennsylvania.

Responding to accusations by the father of a slain Muslim soldier that Donald Trump has “sacrificed nothing,” the billionaire said Saturday that he has made many sacrifices, such as by employing thousands of people.

Khizr Khan, whose son died in Iraq, accused the Republican presidential nominee of vilifying American Muslims, in a steely rebuke that electrified the Democratic convention Thursday.

“Go look at the graves of brave patriots who died defending the United States of America,” Khan said, directly addressing Trump. “You will see all faiths, genders and ethnicities. You have sacrificed nothing and no one.”

Trump brushed off Khan’s words in an interview with ABC News, stating that he thinks he has made “a lot of sacrifices.”

“I work very, very hard. I’ve created thousands and thousands of jobs, tens of thousands of jobs, built great structures. I’ve had tremendous success. I think I’ve done a lot.”

He also suggested that Clinton’s speechwriters penned Khan’s address, which Khan has said he wrote with his wife.

“Who wrote that? Did Hillary’s script writers write it?” Trump said

“If you look at his wife, she was standing there. She had nothing to say,” Trump said, adding that “maybe she wasn’t allowed to have anything to say.”

Among some of Trump’s more controversial policy positions has been his call to ban Muslims from entering the United States.
