Robert O'Brien : John Bolton Without The Mustache? | Trump Names New National Security Adviser

President Trump has named Robert O'Brien, who served as foreign affairs advisor to Mitt Romney's presidential campaign, as his replacement for fired National Security Advisor John Bolton. O'Brien is cut from the exact same neoconservative cloth as Bolton and represents, at most, change in style and physical appearance. With pressure mounting on Trump to attack Iran after unproven accusations that it was involved in an attack on Saudi oil facilities, the President's national security team may find itself without allies in the effort. Will O'Brien put the brakes on Trump's neocons...or will he hit the accelerator?
