On Monday, August 17, 2020, Children's Health Defense filed a lawsuit against Facebook, Inc. in the U.S. District Court, Northern District of California. The lawsuit alleges that Facebook acted jointly or in concert with federal government agencies or actors to deny Children's Health Defense's First Amendment speech and Fifth Amendment property rights. At issue in the case is Facebook's use of fact-checking warning labels and Facebook's disabling of the fundraising feature on Children's Health Defense's Facebook page.
