Washington (CNN) Planned Parenthood announced Monday it will drop federal funding over the Trump administration's rule blocking the reproductive rights organization from talking to patients about abortion services.

"Due to an unethical and dangerous gag rule, the Trump administration has forced Planned Parenthood grantees out of Title X," Alexis McGill Johnson, the acting president and CEO of the organization, said in a phone call with reporters.

Johnson said the organization will continue to fight the rule in court. She said the regulation will "reverberate across the country" and said the move amounted to an "attack on reproductive health care" by the Trump administration.

"We will not be bullied into withholding abortion information from our patients," Johnson said.

The organization previously threatened to pull out of the federal family-planning Title X program rather than participate in the so-called "gag rule."
