Roberts stated I will read your documents, I will review them. Give them to my Secret Service Agent and I will review them. His Secret Service Agent approached me and stated Give me all the documents, I promise you Justice Roberts will get them. I had a full suitcase of documents. The agent went to look for a box, he found a large box to fit all the documents, he showed me his badge, and introduced himself as Gilbert Shaw, secret Service Agent assigned fto the security of Chief Justice Roberts. [underlines are mine].
Chief Justice Roberts isn't guarded by any Secret Service Agent nor or any of the other Supreme Court Justices so guarded. Chief Justice Roberts may have had a guard from the Supreme Court Police Unit or possibly a Federal Marshall assigned to him in this travel.
But I seriously doubt that the Chief Justice identified this guard as a Secret Service Agent or that the Guard identified himself as such...
