Only reason he became controversial was because one murdering racist(Ted Kennedy who kept voting against the Civil Rights Bill until LBJ decided to use it for a political tool) called him a racist without any evidence to back it up.

Sooo, if it was important enough, I'd do my own research, but it's a guy named Bork, sooo...
