The director of the US Secret Service resigned Wednesday following a string of lapses by the elite presidential protection branch, including one in which an armed intruder ran into the White House.
“Today, Julia Pierson, the Director of the United States Secret Service, offered her resignation, and I accepted it,” Homeland Security Secretary Jeh Johnson said in a statement.
Johnson appointed Joseph Clancy to serve as interim acting director until a permanent replacement is named for Pierson, who only took up her post 18 months ago after a prostitution scandal erupted within the agency.
An independent panel will be named to probe the September 19 incident, which saw knife-carrying homeless US army veteran Omar Gonzalez allegedly jump the White House fence and run into the residence, Johnson said.
Gonzalez pleaded not guilty on Wednesday to three counts including unlawfully entering a restricted building or grounds with a deadly or dangerous weapon.
Outraged US lawmakers grilled Pierson on Tuesday over a series of security breaches, including an incident last month in which an armed security contractor with a criminal record was allowed into an elevator with President Barack Obama when he visited Atlanta, Georgia.
White House spokesman Josh Earnest said Wednesday the presidency had only been made aware of the full circumstances of the Atlanta incident shortly before it appeared in a report on Tuesday.
Pierson had vowed to revamp her elite agency as she was subjected to withering criticism by angry lawmakers.
“It’s clear that our security plan was not properly executed,” Pierson said of the September 19 intrusion.
“This is unacceptable and I take full responsibility. And I will make sure that it does not happen again.”
The Gonzalez incident however proved to be the catalyst for Pierson’s departure.
The 42-year-old Iraq veteran’s intrusion triggered widespread incredulity, with lawmakers demanding to know how someone could scale an iron fence, race 70 yards (meters) across a lawn, enter an unlocked White House front door, knock down an agent and run into the East Room without being stopped.
Gonzalez was ultimately tackled by an off-duty Secret Service officer who was walking through the premises, according to reports. A search of a car later revealed hundreds of rounds of ammunition.
