Tom Bossert was abruptly forced out of his job last Tuesday, one day after John Bolton took over as National Security Advisor. Bossert had been advising Mr. Trump since the beginning of his administration. On the heels of this vacancy comes Rob Joyce, the White House Cyber security coordinator, who will be returning to a role at the National Security Agency.
The announcement of Joyce’s departure came just hours after he briefed reporters on a global cyber attack targeting routers and other networking equipment, blaming government-backed Russian hackers targeting US agencies, businesses and critical infrastructure operators.
Joyce is well respected by cyber security experts but DHS Secretary Kirstjen Nielsen called his departure a “natural inflection point when you have a new national security advisor.”
