President Donald Trump’s national security adviser on Wednesday sidelined about 160 National Security Council aides, sending them home while the administration reviews staffing and tries to align it with Trump’s agenda.

In the White House press release, the president ordered that flags be returned to half-staff in honor of the late President Carter.

White House national security adviser Mike Waltz has ordered a “full review” of personnel at the National Security Council (NSC), starting a process to weed out detailees at the agency who are not aligned with President Trump’s agenda.

The Trump administration is screening the loyalty of approximately 160 career civil servants assigned to the National Security Council. Why it matters: The screenings are part of a larger push by President Trump to reshape the federal workforce that includes staffing the administration with loyalists and making it easier to fire civil servants.
