CrossFit has sued two foundations with government ties to have them release information about their donors that may expose potential conflicts-of-interest, including improper relationships with soda companies who give money to fitness groups that are at war with CrossFit.

The lawsuit, filed Thursday under the Freedom of Information Act, accuses the CDC Foundation and the NIH Foundation of being involved in “ethical scandals” by accepting donations from companies that they say have contributed to Type 2 diabetes, liver disease, opioid addiction, and other illnesses. The foundations in question fall outside the government but help to raise money for research at the National Institutes of Health and the Centers for Disease Control and Prevention.
