Protesters gathered at 320 Planned Parenthood clinics around the country on Saturday calling for the end to federal funding for the health care provider.

The Washington Post reports the protesters held signs reading ‘Planned Parenthood Sells Baby Parts’ and participated in prayers and chants.

Controversy over the organization, which provides health services including abortion, erupted recently when undercover videos by anti-abortion activists purported to show Planned Parenthood personnel engaging in illegal activity and selling fetal tissue for profit. Planned Parenthood has denied the allegations, arguing the videos were heavily edited and taken out of context.

In a statement, Planned Parenthood vice president Eric Ferrero said, “These rallies are meant to intimidate and harass our patients, who rely on our nonprofit health centers for basic, preventive health care.”
