The U.S. currency is not the only place where the words show up. A clock and the motto "In God We Trust" over the Speaker's rostrum in the U.S. House of Representatives chamber are seen in Washington, DC.
Michael Newdow has faith in at least one thing: eventually he will win a lawsuit.
The Sacramento doctor and attorney has been on a 14 year quest to remove what he sees as violations of the First Amendment's prohibition against governmental endorsement and support of organized religion.
Newdow has sued to ban prayer at presidential inaugurations, to remove the words "In God We Trust" from American currency and to ban the phrase "under God" from the Pledge of Allegiance.
For years, the 57-year-old has waged his crusade alone and never won a battle. But he plans to appeal a March decision by the 9th Circuit U.S. Court of Appeals against his claim that "In God We Trust" should be removed from currency.
But Newdow has some opposition to his claims. The Pacific Justice Institute is raising funds to help fight his case saying "we simply cannot allow symbols of our national heritage to be discarded for fear of upsetting the most easily offended individuals."
