U.S. President Donald J. Trump has
named Robert C. O’Brien (WaPo), the State Department’s top hostage negotiator, his fourth national security advisor following the departure of John Bolton earlier this month.
O’Brien is seen as a lower-profile and less combative figure than his predecessor, as well as
more politically aligned (FP) with Secretary of State Mike Pompeo. He has emphasized the importance of U.S. global leadership and U.S. alliances. O’Brien joins the administration amid heightened tensions with Iran. The Trump administration is reportedly
weighing responses (NYT), including retaliatory strikes and new sanctions, following attacks on Saudi oil facilities it says Iran may have helped to carry out.
