From the New York Times today:
Khizr Khan, the soldier’s father, lashed out at Mr. Trump in an interview on Saturday, saying his wife had not spoken at the convention because it was too painful for her to talk about her son’s death.
Mr. Trump, he said, “is devoid of feeling the pain of a mother who has sacrificed her son.”...
Mr. Trump told Mr. Stephanopoulos that Mr. Khan seemed like a “nice guy” and that he wished him “the best of luck.” But, he added, “If you look at his wife, she was standing there, she had nothing to say, she probably — maybe she wasn’t allowed to have anything to say, you tell me.”
“They begin to see this person who can hardly speak correct English, who has an accent — and they are saying, ‘How dare he say something of that profound nature?’ Not profound in their eyes, but profound in how many people have responded,” said Khan, a Harvard-trained lawyer who lives in Charlottesville, Va.
