Obama names Julia Pierson to be first female director for Secret Service

President Obama on Tuesday named U.S. Secret Service agent Julia Pierson to be the agency's new director, the first woman to hold that post.

"Julia is eminently qualified to lead the agency that not only safeguards Americans at major events and secures our financial system, but also protects our leaders and our first families, including my own," Obama said in a statement, highlighting Pierson's 30 years of service.

"Julia has had an exemplary career, and I know these experiences will guide her as she takes on this new challenge to lead the impressive men and women of this important agency," he added.

Pierson, currently the agency's chief of staff, will succeed Mark Sullivan. Sullivan retired as director in January after serving with the Secret Service for roughly three decades.

He came under intense scrutiny from Congress over the last year as lawmakers investigated the agency's handling of an incident in Cartagena, Colombia, in which agents invited prostitutes back to their hotel rooms during an assignment.

Sullivan said he was "dumbfounded" by the scandal and said the incident was not common for the agency.

Six agents were dismissed or reassigned after the incident, which angered lawmakers and marred the agency's reputation.

“During the Colombia prostitution scandal, the Secret Service lost the trust of many Americans, and failed to live up to the high expectations placed on it,” said Grassley.

“Ms. Pierson has a lot of work ahead of her to create a culture that respects the important job the agency is tasked with.  I hope she succeeds in restoring lost credibility in the Secret Service.”

Before her post as chief of staff, Pierson served as the agency's assistant director of the Office of Human Resources and Training. Before joining the Secret Service, she was an officer with the Orlando Police Department.

Obama's selection of Pierson follows intense criticism over the perceived lack of diversity in his second-term appointments.
