Republican presidential candidate Donald Trump said the United States needs to authorize "something beyond waterboarding" in order to better fight terror groups. Trump justified the use of waterboarding and other unnamed advanced interrogation techniques because terror groups use greater measures to inflict fear and harm. He added that groups like ISIS go well beyond waterboarding. "I would absolutely authorize something beyond waterboarding and believe me, it will be effective," he said Sunday on ABC's "This Week With George Stephanopoulos." "You have our enemy cutting heads off of Christians and plenty of others, by the hundreds, by the thousands." "Do we win by being more like them?" asked Stephanopoulos. "Yes," replied Trump. "I'm sorry. You have to do it that way."
