The Supreme Court has declined to hear a lawsuit brought by Health Secretary Robert F. Kennedy Jr.’s anti-vaccine group that claimed Meta had illegally censored the organization’s social media posts.

The justices ruled that a key preventive health task force has authority because it is appointed by the Health and Human Services secretary. Some experts worry that RFK Jr. could politicize it.

Children's Health Defense argues its First Amendment rights were violated when Facebook restricted its anti-vaccine posts.
