Supreme Ethics Problem?

The subhead to this report by Brian Ross of ABC News asks

What Was Supreme Court Justice Antonin Scalia Doing on Day of Supreme Court Swearing-In?

One of our posts from June 28, 2005 links to an announcement that on September 29-30, 2005 Justice Scalia would be teaching at a seminar in Colorado presented by the Federalist Society. Despite that, ABC News labels this item "EXCLUSIVE" and says "ABC News has learned..." apparently meaning it has just learned about this.
