Margaret Brennan sat down with President Donald Trump's pick for his National Security Advisor, former Representative Mike Waltz, on Sunday, January 19th for an extended interview about foreign policy and national security during the second Trump presidency.

Trump’s national security adviser Mike Waltz had signaled before Inauguration Day that he would look to move holdover civil servants that served in the NSC during President Joe Biden’s administration back to their home agencies. The move is meant to ensure the council is staffed by those who support Trump’s agenda.

The White House is sidelining around 160 detailees from the National Security Council to align with President Trump's agenda.

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.

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.

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.
