There's a whole lot of this slanderous garbage on extremist sites. They appear to have conveniently started when McCain called out the Communist Putin's Ally Trump. I tried to find any credible official records to corroborate them and could not. I did find the following from people I have met, knew or worked with:
“Some people act tough. John’s the real thing. When the Vietnamese would make demands of him, he just stood up to them all the way, to the point of risking a lot more torture. They didn’t have him cowed at all. He’s just as honest as the day is long, and courageous to the extent of always doing the right thing, no matter what.”--John McCain's cellmate Bob Schumaker
“Having gone through an experience when you’re living on the brink of death day-to-day gives you a different perspective on life, on humanity, and on what’s important. An experience like [POW camp] teaches you to recognize right from wrong, and how to be faithful to your values under fire. John’s done this.”--Everett Alvarez, America's longest held POW
“It’s what John did with his life after Vietnam that impressed me so much. If you look at his political career, he has always spoken his mind about what he thinks is right, regardless of the consequences.”--Ex-POW Air Force Maj. Gen. Ed Mechenbier
"I consider it blasphemy to smudge the straight-arrow prisoner-of-war
record of a man who was near death when he arrived at Hoa Loa prison 1967:
both arms broken, left leg broken, left shoulder broken by a civilian with a
rifle butt.
He was eventually taken to the same rat-infested hospital room I had
occupied two years earlier, and, like me, he had surgery on his leg. By then the
Vietnamese had discovered that his father was the ranking admiral in the
Pacific Fleet, and he received an offer that, as far as I know, was made to
no other American prisoner: immediate release, no strings attached. He
refused, thereby sentencing himself to four more years in a cell."--Adm. John Stockdale, ranking officer "Hanoi Hilton," Medal of Honor winner
I'll take these guys opinions of McCain over the extremist bloggers who in support of the Communist Putin's Ally Trump's, slander of this brave American.
