not until later in 1998, Harvard Law hired civil rights attorney and U.S. assistant attorney general nominee Lani Guinier, who became the law school's first black female tenured professor. In March 2012, five months after his death, Bell became the target of conservative media, including Breitbart and Sean Hannity, in an exposé of President Barack Obama. The controversy focused on a 1990 video of Obama praising Bell at a protest by Harvard Law School students over the perceived lack of diversity in the school's faculty. Bell's widow stated that Bell and Obama had "very little contact" after Obama's law school graduation. She said that as far as she remembered, "He never had contact with the president as president." An examination of Senior Lecturer Obama's syllabus for his course on race and law at the University of Chicago revealed significant differences between Obama's perspective and that of Derrick Bell, even as Obama drew on major writings of critical race theory. Critical race theory Bell is arguably the most influential source of thought critical of traditional civil rights discourse. Bell's critique represented a challenge to the dominant liberal and conservative position on civil rights, race and the law. He employed three major arguments in his analyses of racial patterns in American law: constitutional contradiction, the interest convergence principle, and the price of racial remedies. His book Race, Racism and American Law, now in its sixth edition, has been continually in print since 1973 and is considered foundational in the field of critical race theory. The 1954 Brown V. Board of Education case ignited Bell's interest in studying racial issues within the education system. This was due to the Supreme Courts decision and its evident lack of progress for black students. During the 70s, Bell studied and wrote about the effects of desegregation noting that this decision was not due to a moral shift in nature, but rather because of the "convergence" of efforts in dismantling Jim Crow laws and racial segregation. Additionally, it had to do with the concern of the white elite that the United States would lose the battle to communism, and tarnish their reputation and global influence. The injustices initially set by segregation were not undone but, instead created new issues for black students at predominantly white institutions. Consequently, Bell comes to the conclusion that American educational systems should focus on improving the quality of education for black students,
