More than 100 National Security Council officials have been removed from their roles or detailed back to their agencies, part of a broader restructuring process under Secretary of State Marco Rubio who is also serving as interim national security adviser.

President Donald Trump is ordering a massive overhaul of the National Security Council that will shrink its size and return many career appointees back to their home agencies.

The staff sent home included both career officials who were detailed to the NSC, as well as some political appointees.
