"All references to the National Security Staff or Homeland Security Council Staff in any executive order or presidential directive shall be understood to refer to the staff of the National Security Council," Obama said in the one-page order.
In a blog posted on WhiteHouse.gov, NSC spokeswoman Caitlin Hayden said, "[We] are once again the National Security Council staff."
The name was changed to National Security Staff in 2009, when the Obama administration combined the National Security Council staff and the Homeland Security Council staff, Hayden said.
"The original goal was to end the artificial divide between White House staff dealing with national security and homeland security," Hayden said. "Given that the merger has done just that, and we are well aligned and organized to meet complex 21st century threats with the reorganization, we can revert to our historic and well recognized name, while maintaining a strong sense of cohesiveness and unity in supporting the president and the principals on his national security team."
National Security Council staff was the name used from the signing of the National Security Act of 1947 until 2009.
