President Donald Trump appointed John Bolton, former U.S. Ambassador to the United Nations, as his National Security Advisor (NSA) effective as of April 9th, 2018.
The move, replacing Lt. Gen. H.R. McMaster is but the latest of high-level personnel changes in the Trump administration, but perhaps not the last. Mike Pompeo recently was selected to succeed Rex Tillerson as Secretary of State and is now pending Senate Confirmation. Trump’s Chief of Staff John F. Kelly may yet depart as well, and even the Secretary of Defence James Mattis could be eventually replaced.
