It seems that Donald Trump may appoint Brian Hook, special representative for Iran and senior advisor to the secretary, as the US national security adviser. Last year many times Brian Hook was against the policies’ of John Bolton and US National Security Council.
He was close to Rex W. Tillerson who put pressure on Trump not to exit the Joint Comprehensive Plan of Action (JCPOA). Although Tillerson was fired, Brian Hook still is working in the same position and now its name is heard as one of the major candidates to substitute Bolton!
It is worth noting that Brian Hook was the leader of a group against Trump in 2016 election!
