Planned Parenthood, under fire for a heavily-edited video suggesting the organization violated federal law in facilitating the donation of fetal tissue, says it believes future videos may make racially-charged claims. The health provider and advocacy group also says the anti-abortion group posing as a medical research procurement company may have had access to the inside of its clinics, jeopardizing “our patients’ privacy and dignity.”

The new information was disclosed in a letter from Planned Parenthood’s senior counsel, Roger Evans, in response to a request from a congressional committee that the doctor depicted in the video appear there for questioning. The Center for Medical Progress, a group that appears to have been formed for the sole purpose of secretly recording Planned Parenthood and other abortion providers, has said it plans to release a video a week.
