Yesterday, Julia Pierson, a highly respected veteran of the Secret Service, was sworn in as the Director of that agency in a ceremony with President Obama and Vice President Biden in the Oval Office.  Julia PIerson brings 30 years experience to the agency and the hope is that she will bring about a change in the culture of the institution after the prostitution scandal.  13 Secret Service employees were involved in the scandal just before the summit at the city of Catagena, Colombia which embarrassed the U. S. delegation.
