The Washington Post reports:
Secretary of State Mike Pompeo says he isn’t running for Senate next year. Those close to him say he hasn’t made a final decision yet. But that hasn’t prevented a barely concealed competition from breaking out within the administration over who might replace him as the nation’s top diplomat. President Trump has fueled the fire by sounding out lawmakers and officials as he considers his options.
The person most often mentioned to succeed Pompeo is national security adviser Robert O’Brien. Trump really likes O’Brien, several officials told me, and has given him increased diplomatic responsibilities since he became the president’s fourth national security adviser in September. O’Brien stood in for Trump at the Association of Southeast Asian Nations summit in Thailand in October.
