Court documents say President-elect Barack Obama asked to invoke God . Michael Newdow , supported by several groups including the American Humanist Association , claims in his lawsuit that `` so help me God '' violates the constitutional ban on government `` endorsement '' of religion . Groups are suing to block any mention of God during the inaugural ceremonies . The Supreme Court is expected to rule on whether a public official can use his or her office for religious purposes in coming weeks.
