Daniel Sickles
In 1859 Sickles was arrested for murder. His wife had turned to another man for attention. This was Francis Barton Key, son of Francis Scott Key. Sickles repeatedly shot Key in front of his home (which was also in front of the White House. Sickles had a team of lawyers represent him, led by Edwin M. Stanton (future Secretary of State under Abraham Lincoln). Sickles was released on what was the first successful plea of "temporary insanity". Sickles already had a questionable reputation, but this incident made him a pariah. Sickles saw the outbreak of the civil war as an opportunity to save his reputation.
