Robert O'Brien becomes the new National Security Advisor to US President Donald Trump. The president announced this on Wednesday.
O'Brien hereby becomes the fourth safety advisor in a row under Trump. He succeeds John Bolton, who was fired by the president last week.
The security adviser was active as a special hostage envoy at the Ministry of Foreign Affairs. He negotiated on behalf of the US government during hostage-taking abroad.
O'Brien was sent to Sweden by the president this summer to negotiate the release of American rapper A $ AP Rocky, who was detained there as a suspect of assault.
"I have been working well with Robert for a long time. He will do great," tweeted Trump on Wednesday.
I am pleased to announce that I will name Robert C. O'Brien, currently serving as the very successful Special Presidential Envoy for Hostage Affairs at the State Department, as our new National Security Advisor. I have worked long & hard with Robert. He will do a great job!Avatar
Four safety advisers in a few years
The previous security adviser Bolton was fired after disagreement with the president about the security approach in Venezuela and North Korea.
O'Brien's other predecessors, Herbert McMaster and Michael Flynn, also had no long career as a safety adviser. McMaster was fired because he was too rigid and Flynn because he lied to the American security service FBI.
