The Trump administration has put more than 100 officials at the National Security Council at the White House on administrative leave on Friday as part of a restructuring under interim national security adviser and Secretary of State Marco Rubio.

Axar.az reports, citing CNN, a significant overhaul of the body in charge of coordinating the president’s foreign policy agenda was expected in the coming days, including a staff reduction and a reinforced top-down approach with decision-making concentrated at the highest levels.

An email from NSC chief of staff Brian McCormack went out around 4:20 p.m. informing those being dismissed they’d have 30 minutes to clean out their desks, according to an administration official. If they weren’t on campus, the email read, they could email an address and arrange a time to retrieve their stuff later and turn in devices.

Staffed by foreign policy experts from across the US government, the NSC typically serves as a critical body for coordinating the president’s foreign policy agenda.

But under President Donald Trump, the NSC’s role has been diminished, with the overhaul expected to further reduce its importance in the White House.
