Republican U.S. congressional leaders on Wednesday launched an investigation of Planned Parenthood after a video implying it sells the organs of aborted fetuses was released on the Internet. The reproductive health group said the video is false.

The secretly recorded video shows Dr. Deborah Nucatola, senior director of medical services at Planned Parenthood Federation of America, discussing harvesting body parts from aborted fetuses with actors posing as buyers from a biological company. The conversation took place over lunch and wine in a restaurant.

The Center for Medical Progress, the California-based anti-abortion group that released the video on Tuesday, said it was evidence that Planned Parenthood was involved in the illegal sale of aborted fetuses and conducting illegal partial-birth abortions.
