The U.S. Justice Department is planning to investigate and possibly sue universities over admissions policies that discriminate against white applicants, the New York Times reported on Tuesday, citing a department document.

The internal memo seeks lawyers in the department's civil rights division who are interested in working on a new project on "investigations and possible litigation related to intentional race-based discrimination in college and university admissions," the Times reported.

The U.S. supreme court has ruled that universities may use affirmative action admissions policies, which are intended to give minority applicants an edge in getting into college. The court has rejected racial quotas but said race could be used as one factor among many in evaluating an applicant.

Critics of affirmative action say that in some cases it goes too far in discriminating against white and Asian-American applicants.

The Times said the department document does not explicitly say whom it considers at risk because of affirmative action admissions policies. But the Times reported that supporters and critics of the project said it clearly targeted admissions programs that seek to help black and Latino students.

A Justice Department spokesman told Reuters the department would not comment on personnel matters.

The Times said the document suggests the project will be run out of a part of the civil rights division where its political appointees work, rather than the educational opportunities section, which is devoted to handling cases involving universities and is run by career civil servants.
