Michael Newdow was in court back on December 4, 2007. Newdow agued both the Pledge Case and the Motto Case just two days before Romney presented his Faith in America speech. See http://www.law.com/jsp/article.jsp?id=1196762679367 . The full oral argument can be found at http://www.ca9.uscourts.gov/ . Select "Audio Files, and put in "05-17257" for the Pledge case. For the Motto case, put in "06-16344".
Explicit Atheist, Michael Goldstein wrote an excellent blog ( http://explicit-atheist.blogspot.com/ Jan. 20, 2008) that resulted from a presentation of Kevin Hasson of the Becket Fund that was delivered during the Pledge Case. It's definitely worth reading.
