US Senator John McCain has said it was “wrong” how wealthy Americans avoided the Vietnam War draft in a remark which many view as an attack on Donald Trump.
The rich “found a doctor that would say that they had a bone spur”, he said in an interview with C-SPAN, appearing to refer to Mr Trump’s 1968 diagnosis.
Mr McCain on Monday faulted “the system” for allowing Americans like Mr Trump to evade service.
The remark is the latest in a string of clashes between the two Republicans.
In an interview on Sunday marking the 50th anniversary of being shot down over North Vietnam, Mr McCain spoke about his service as a Navy pilot and his experience as a prisoner of war.
“One aspect of the conflict, by the way, that I will never ever countenance is that we drafted the lowest-income level of America, and the highest-income level found a doctor that would say that they had a bone spur,” he said.
