 The head of the local NAACP charged that the school only made the non-discriminatory pledge so it could retain its tax deduction while knowing no blacks would enroll due to the high tuition.The IRS decision to grant tax exempt status to the school was investigated by Senate Select Committee on Equal Education Opportunity.Senator Walter Mondale asked IRS commissioner Randolph W. Thrower to explain why the school had been granted tax exempt status in light of reports the school's headmaster told an undercover NAACP investigator that "no black applicants were expected" but the investigator's children could apply if they "had $750 in their ass pocket."
