The primary trade association representing U.S. doctors offers race-based scholarships through its philanthropic arm, something a conservative medical group argues could disqualify it from holding a tax-exempt status.

Do No Harm filed a complaint with the IRS on Tuesday detailing a number of scholarships offered by the American Medical Association Foundation that are racially exclusive. One such scholarship is available only to black medical students, another was available only to students who aren’t Asian or white, and a third was offered only to applicants of “Eastern European descent.”
