Last year John McCain sneaked across the Syrian border to hold a meeting with some of the country’s rebels. As it turns out some of those rebels ended up in ISIS. While we didn’t know what he discussed with the rebels at the time we now know:
At least four hostages held in Syria by the Islamic State, including an American journalist who was recently executed by the group, were waterboarded in the early part of their captivity, according to people familiar with the treatment of the kidnapped Westerners.
If anybody knows how to waterboard people it’s John McCain!
