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.
