Donald Trump responded to an appearance by a Muslim lawyer at the Democratic convention by saying he "would like to hear his wife say something."

One of the highlights of the Democratic convention in Philadelphia was a speech by Muslim lawyer Khizr Khan, who was accompanied by his wife Ghazala, about their son, a Marine who died in Iraq back in 2004. Khan at one point held up a pocket-sized version of the Constitution and asked if Trump ever read it.

"I'd liked to hear his wife say something," Trump said in an interview with New York Times columnist Maureen Dowd.

Trump elaborated on Khan's comments during an excerpt of an interview with George Stephanopoulos on ABC's This Week that will air Sunday.

"Maybe she wasn't allowed to have anything to say, you tell me," he said.

Ghazala Khan did speak Friday, after the convention, during an interview with Lawrence O'Donnell on MSNBC.

When pressed by Stephanopoulos about Khan's statement that Trump has sacrificed nothing, Trump asked if Hillary's speechwriters wrote that line.

He then said that he has employed thousands of people. "I think those are sacrifices," he said.

Trump's has previously said he wanted to temporarily ban all Muslims who are not citizens from immigrating into the U.S. due to terrorism concerns, but he changed it to a ban on immigration from countries that breed terrorism.

Interestingly, and perhaps with some irony, Trump used the same phrase when asked about Bernie Sanders.

"I think he wanted to go home and sleep. I'd like to hear his wife say something," Trump said.

Sanders' wife Jane has appeared on TV several times during the primary campaign. She recently told CNN she couldn't explain why die-hard supporters of her husband's campaign won't unify behind Clinton to defeat Trump.
