The Justice Department's Office of Civil Rights has launched investigations into three U.S. medical schools over concerns about race-based discrimination in their admission processes.

The investigations, led by Assistant Attorney General Harmeet Dhillon, are into Stanford and Ohio State universities and the University of California San Diego, according to The Hill newspaper. 

Dhillon's office requested the schools provide seven years of data about applicants’ race, standardized test scores, relations to donors, zip codes and other educational information by April 24. 

"Launching a series of civil rights investigations," Dhillon posted on X. "Another day in paradise!"

The department has not commented on the investigations so far, but the schools confirmed they received the letters and said they would respond appropriately.

"Ohio State is fully compliant with all state and federal regulations and legal rulings regarding admissions," Benjamin Johnson, a spokesman for The Ohio State University, told NBC News.

The investigations come after the Trump administration investigated multiple schools last year over their diversity, equity and inclusion policies. The DOJ also sued Harvard last month for withholding its race-based admission documents.
