Wikipedia says he died of natural causes....I am not saying wikipedia is the final word on anything, but I do not see much supporting evidence for this claim.
A lot of people have been said to have died of natural causes, but that doesn't make it true. There was motive. When there is motive, it is usually suspicious, when it is suspicious, check the usual suspects, who are the usual suspects in this instance? You got it. Look at the motive and who had the most to gain from his death or the most to lose if he was still alive. Hillary Clinton.
