"Does he have tax payer funded health insurance?"
Of course he does, as do 44M enrolled in Medicare. As a retired military member he is entitled to free health care, either from the VA or Tricare insurance. He also has Medicare which the member pays a small amount  but primarily funded by then taxpayer.   
You may be insinuating he has free health care because of his status in government - he doesn't. All of his insurance benefits have been earned.
