William McRaven said the Osama bin Laden conspiracy theory boosted by President Donald Trump was as crazy as denying the moon landing. "I didn't even think it was worth addressing because it was so crazy," the former head of US Special Operations Command said during a CNN interview Tuesday. McRaven added that he was glad to see that Robert O'Neill, a fellow former Navy SEAL and a former member of SEAL Team 6 who is said to have shot bin Laden, speak out against the conspiracy theory.
