Loyalty matters most in race to become Trump’s next national security adviser

Marco Rubio and Stephen Miller, White House cronies with very different backgrounds, are up for Mike Waltz's old post

The race is officially on to become Donald Trump's next national security adviser - but in this White House, the personalities and egos surrounding the president can matter far more than the titles they hold.

Speaking from Air Force One on Sunday evening, Trump suggested secretary of state Marco Rubio could continue to double-hat as the interim national security adviser. But he also praised Stephen Miller, whom he said was at the top of the totem pole" for the appointment and said he was in effect already doing the job.
