John McCain married a beautiful model right after he graduated from Annapolis - at the bottom of his class, BTW. While he was a prisoner she campaigned endlessly for POWs and MIAs.
One night, coming home from the POW event she was badly injured in an automobile accident. When Mccain came home he found that she was very disabled. He began dating a very wealthy and attractive woman and dumped his disabled wife for this much younger wife.
McCain still pays for his first wife's medical bills.
With whose money? As a dependent when injured, she would be entitled to dependent's medical care, and the taxpayer would pay.
