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.

WASHINGTON (AP) — 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, according to two U.S. officials and one person familiar with the reorganization.

The dismissals, part of plan to radically downsize the National Security Council, follow President Donald Trump’s recent ouster of his national security adviser.
