Draft dodging Donny defends dubious deferments...

The deferment was one of five Mr. Trump received during Vietnam. The others were for education.

His experience during the era is drawing new scrutiny after the Muslim American parents of a soldier who was killed in Iraq publicly questioned whether Mr. Trump had ever sacrificed for his country. In an emotional speech at the Democratic National Convention last week, the soldier’s father, Khizr Khan, directly addressed Mr. Trump, the Republican presidential nominee, saying, “You have sacrificed nothing and no one.”

Mr. Trump’s public statements about his draft experience sometimes conflict with his Selective Service records, and he is often hazy in recalling details.

In an interview with The New York Times last month, Mr. Trump said the bone spurs had been “temporary” — a “minor” malady that had not had a meaningful impact on him. He said he had visited a doctor who provided him a letter for draft officials, who granted him the medical exemption. He could not remember the doctor’s name.

“I had a doctor that gave me a letter — a very strong letter on the heels,” Mr. Trump said in the interview.
