In a rare public appearance, a group of nuns stood before the Supreme Court Wednesday to rally against a provision in the Affordable Care Act that they believe forces them to violate their deeply-held religious beliefs.

The provision, often called the “contraceptive mandate,” requires employers, including the Little Sisters of the Poor, to offer coverage for birth control, sterilization and abortifacients.

The Daily Signal spoke to Sister Veronica Proffitt, who has served the sick and elderly with the Little Sisters of the Poor for more than 30 years. Watch the video to hear her story, along with others who attended the rally.
