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).
There are only two impeached presidents in United States history, meaning only two presidents have been charged by the House of Representatives with committing high crimes and misdemeanors. Neither of the two impeached presidents, Andrew Johnson and Bill Clinton, were convicted by the Senate. In fact, there has never been a president removed from office using the impeachment process. There is only one other mechanism set forth in the U.S. Constitution, aside from conviction on impeachment charges, that allows for the removal of a failing president.
