A conservative legal group with ties to President Donald Trump filed a lawsuit Tuesday against several federal health agencies, including the Department of Health and Human Services, for failing to hand over internal records from the Biden administration’s alleged plans to prioritize organ transplants based on race and ethnicity.

In a lawsuit filed Tuesday, America First Legal, a firm founded by White House deputy chief of staff Stephen Miller, accused HHS, the Centers for Medicare and Medicaid Services, and the Health Resources and Services Administration of stonewalling a public records request related to the organ transplant programs that America First Legal filed more than a year ago under the Freedom of Information Act.
