Becket Fund Challenges Atheist Lawsuit Over Obama Oath
Michael Newdow, the atheist attorney best known for trying to remove the words “under God” from the Pledge of Allegiance, announced Dec. 29 that he is filing a lawsuit in the U.S. District Court for the District of Columbia, to forbid references to God during the presidential inauguration ceremony for Barack Obama, January 20.
“Newdow’s lawsuit over the inauguration is a lot like the streaker at the Superbowl: a pale, self-absorbed distraction. And anybody who looks at it carefully can see there’s not much there,” said Scott Walter, executive director of the Becket Fund for Religious Liberty.
