If I may pose a question; I recall reading somewhere that Obama was given a Secret Service detail earlier than usual, but not sure if it was that far back to last July.
But if it was, isn’t their itinerary and travel schedule a matter of public record? How could we go about checking to see where they were on that date?
Good point and yes it did. Found your answer: May 3, 2007 (so about two-and-a-half-months prior to July 22 of that year).
