John Bolton, a former US diplomat, took over the role of National Security Advisor, yesterday. Trump had fired his National Security Advisor Lt Gen HR McMaster last month. “The president is grateful for Tom’s commitment to the safety and security of our great country,” White House Press Secretary Sarah Sanders said. “Tom led the White House’s efforts to protect the homeland from terrorist threats, strengthen our cyber defences, and respond to an unprecedented series of natural disasters. President Trump thanks him for his patriotic service and wishes him well,” Sanders said. In March, one of Trump’s longest-serving and trusted aides Hope Hicks resigned as the powerful communications director. Also, White House’s top economic adviser Gary Cohn resigned over his differences with Trump on trade policy.  Trump last month also sacked Rex Tillerson as Secretary of State and replaced him with CIA director Mike Pompeo.
