7. Was he poisoned?
Of the many presidential mysteries that the United States has, this one is truly strange. On August 2, 1923, it was a summer day when President Warren G. Harding was with his wife. Everything was going well; his wife was reading him an article from The Saturday Evening Post, and all of a sudden he dropped dead.
After the incident, an autopsy was requested, but his wife insisted that there was no need for one. This raises so many suspicions that maybe she is the one who poisoned him.
A different hypothesis claims that Harding, our 29th president, died at the age of 57 from a typical case of heart failure. This hypothesis is based on an examination of Harding’s declining health in the days preceding his passing.
