Causes of Abnormal Mucus in the Stool. Examples of conditions that can be responsible for abnormal mucus in the stool can include Irritable Bowel Syndrome--including Ulcerative Colitis and Crohn's Disease (an extremely inflammatory condition)--infection and mechanical obstruction.
Assassination and Death. Four sitting Presidents have been assassinated while in office: Abraham Lincoln, James Abram Garfield (1881), William McKinley (1897-1901), and John F. Kennedy (1961-63).
As with his brother John's death, Kennedy's assassination and the circumstances surrounding it have spawned a variety of conspiracy theories. Kennedy remains one of only two sitting United States Senators to be assassinated, the other being fellow Democrat Huey Long in 1935.
