Trump's deputy National Security Adviser Ricky Waddell will leave the White House, according to two sources briefed on the decision. New National Security Adviser John Bolton wants to bring his own person in, and Waddell was H.R. McMaster's hand-picked deputy.
Behind the scenes: John Kelly loves Waddell, who used to work with him in the military. Kelly not only wanted to keep Waddell on the NSC, but suggested to Trump that Waddell — not Bolton — should replace McMaster as the National Security Adviser. He was overruled, and now Bolton appears to have total authority of hiring and firing on the NSC.
