There is no evidence that any U.S. President was killed by poison.
While there have been several instances of assassination attempts and conspiracies involving U.S. presidents, none have been definitively proven to involve poisoning. The most well-known example is the assassination of Abraham Lincoln, who was shot by John Wilkes Booth.
Other presidents have faced assassination attempts, including:
- Andrew Jackson: Survived an assassination attempt in 1835.
- Theodore Roosevelt: Survived an assassination attempt in 1912.
- Franklin D. Roosevelt: Faced several assassination attempts during his presidency.
- Harry S. Truman: Faced an assassination attempt in 1950.
- John F. Kennedy: Assassinated in 1963.
- Gerald Ford: Faced two assassination attempts in 1975.
- Ronald Reagan: Survived an assassination attempt in 1981.
While the possibility of poison being used in a presidential assassination cannot be entirely ruled out, there is no historical evidence to support this claim.
