Freedom From Religion Foundation
The Freedom From Religion Foundation (FFRF) is a nonprofit educational organization devoted to maintaining the separation of Church and state, and educating the public about nontheists.
Dan Barker and Annie Gaylor act as co-presidents of the organization.
The organization's newsletter is Freethought Today, which publishes 10 issues annually.
FFRF has filed numerous lawsuits against violations of church-state separation. Cases include removing the Ten Commandments from public property, challenging Faith-based initiatives, and stopping government funding of a religious school.
