Quick Answer

In the case of Zachary Taylor, forensic evidence gathered in the 1990s ruled out the possibility of poisoning, though the rumors of President Harding's demise were never officially cleared up. His wife refused to allow an autopsy and had hired a private investigator to look into her husband's known infidelities, leading some to speculate that Mrs. Harding killed her husband.

In President Harrison's case, his death while in office came only one month after his inauguration speech, making him the shortest serving president in history.
