McCain, granted it was under duress, broke the Code of Conduct, and UCMJ laws of the day, by speaking out against the U.S.. I long admired him for what he endured, despite that lone “failure”. I didn’t agree with his “politics”, but still respected him.
His turning on Bergdahl now, after also calling for his return, for years, and his support of “W” for years, is simply one more sad disappointment. Go home, John, it’s time.
