The Department of Justice has opened a probe into the role of race in Harvard University's admissions policies and is threatening to sue unless Harvard turns over documents by a Dec. 1 deadline, according to correspondence obtained by NPR.The investigation is looking into allegations that the elite university's admissions policies discriminate against white and Asian-Americans seeking admission by holding them to higher standards than black and Latino applicants. These are claims also made in a 2014 federal court case filed by the anti-affirmative action group Students for Fair Admissions, which remains pending."Harvard has publicly stated that its admissions policies and ongoing efforts to enroll a racially and economically diverse student body are in compliance with the 1964 Civil Rights Act," reports NPR's Claudio Sanchez. "Title VI of that law prohibits federally funded institutions from discriminating on the basis of race, color or national origin." A Nov. 17 letter from the Department of Justice Civil Rights Division says that the U.S. has determined that Harvard is "not complying with its Title VI access requirements." Another letter from the same division says that in the two months since the initial request for information, "Harvard has pursued a strategy of delay and has not yet produced even a single document." The Justice Department is seeking "broad-ranging access to documents regarding Harvard's admissions policy and practices." It criticizes Harvard's questioning of why the Civil Rights Division is involved in the matter, saying it was delegated by the Department. Earlier correspondence from Harvard's lawyer to the Justice Department obtained by NPR suggests the university's skepticism about the probe."[T]he opening of an investigation in the current circumstances is, to our understanding, so outside ordinary practices that Harvard is obliged to clarify the authority and rationale for the Department's decision," Harvard lawyer Seth Waxman's letter reads.He states that the complaint at the core of this investigation is two and a half years old, and is "even more unusual because, as you know, identical issues are being litigated in federal court."As Kirk Carapezza reported for NPR, when the complaint was made initially "the Obama administration dismissed the claim without evaluating its merit" due to the pending lawsuit. In August when the probe was confirmed, legal experts told Carapezza that they were skeptical about the allegations of race-based discrimination:
