StemExpress, one of the tissue companies that works with Planned Parenthood, is cutting its ties with the women’s health organization after a series of sting videos that have prompted congressional inquiries, sources tell POLITICO.

The small biomedical tissue procurement company is distancing itself from Planned Parenthood after finding itself tangentially linked to what abortion opponents allege is Planned Parenthood’s illegal trafficking of fetal tissue and organs.

Both StemExpress and Planned Parenthood have denied doing anything illegal or improper. They say that they only facilitated the donation of tissue for medical research with a patient’s consent.

StemExpress, a five-year-old company based in Placerville, Calif., notified Planned Parenthood and Congress Friday of its decision to end the relationship, the source said. The House Energy and Commerce and the Senate Judiciary committees had asked StemExpress to explain its relationship with Planned Parenthood.
