Via Lachlan Markay at Heritage, we learn a Derrick A. Bell visited the Obama White House twice in 2010. The White House did not return a request for comment. The visits were on 1/29/2010, a Friday and 1/31/2010, a Sunday. For now, a web search of news reports did not turn up why Bell may have been in Washington that particular weekend.

Heritage could not independently confirm that the Derrick A. Bell listed is the same individual who spoke at the rally. The White House did not return a request for comment.

In the video, Obama tells the crowd to “Open your hearts and open your minds to the words of professor Derrick Bell.” Those words tended to be quite controversial. Bell is widely credited with pioneering the field of Critical Race Theory, a radical school of legal thought that holds that the American legal and political systems are inherently racist.
