Number: 36th president
TermNov. 22, 1963 – Jan. 20, 1969

Lyndon B. Johnson is considered a champion of civil rights because he passed the 1964 Civil Rights Act and the 1965 Voting Rights Act, and focused on taking down the KKK. But the man didn't have a way with words, and constantly chose to use the word "n****r" like it was his own name. He even called the Civil Rights Act the "n****r bill." 

In Lone Star Rising: Lyndon Johnson and His Times, 1908-1960, by Robert Dallek, Johnson reportedly defended appointing Thurgood Marshall to the Supreme Court to a staff member by saying, "Son, when I appoint a n****r to the court, I want everyone to know he's a n****r."
