In addition to The Pioneer Fund, Draper financed the Back to Africa repatriation movement, particularly the work of Earnest Sevier Cox whose book "White America" he also funded. During the civil rights movement of the 1960s he secretly sent $255,000 to the Mississippi State Sovereignty Commission in 1963 and 1964 to support racial segregation. He had also promoted opposition to the desegregation of public schools mandated by the Supreme Court's 1954 decision, Brown v. Board of Education. These financial contributions came to light in the 1990s, when the Sovereignty Commission records were made public. Doug A. Blackmon of "The Wall Street Journal" and Prof. William H. Tucker of Rutgers University discovered the incriminating documents.
