I want to know the answer to the following question:
What organization sought to strip Washington University of its tax-exempt status in the 1940's?
All the background I'm provided with is that "During the mid and late 1940s, the University was the target of critical editorials in the local African American press, letter-writing campaigns by churches and the local Urban League, and legal briefs by the NAACP intended to strip its tax-exempt status.". Is that enough to answer the question?
