McMaster out, Bolton in as National Security Adviser
H.R. McMaster plans to resign and will be replaced as national security adviser by former U.N. ambassador John Bolton. The White House said McMaster's departure had been under discussion for some time and that the process was sped up to end speculation about the role. McMaster will stay on until mid-April.
Bottom line: This isn’t about ideology — unlike Trump, Bolton is hawkish and interventionist on foreign policy. This is about personal chemistry.
