US President Donald Trump on Wednesday appointed Robert O’Brien as the new National Security Advisor, replacing John Bolton.
Trump made the announcement on Twitter, promising that O’Brien, who previously served as Special Presidential Envoy on Hostage Affairs at the State Department, will do a “great job” as the fourth NSA in this administration.
The president and his new appointee spoke with reporters on Wednesday morning in Los Angeles.
“Robert has been fantastic,” Trump said, praising O’Brien’s work with hostages. “We know each other well.”
O’Brien said it was a “privilege” to take on the role.
“We’ve got a number of challenges but there’s a great team in place,” he said. “I look forward to working with them and working with the president to keep America safe and continue to rebuild our military.”
O’Brien will be the fourth National Security Advisor to serve in the Trump administration, following Michael Flynn, H. R. McMaster, and John Bolton.
