The internal battle taking place in the Trump administration, pitting the "adults" – Secretary of State Rex Tillerson, Secretary of Defense James Mattis, General John Kelly, and National Security Advisor H. R. McMaster – against the "America First" nationalists, led by Steve Bannon and Stephen Miller, has now spread to the media. At the center of the controversy is McMaster, whose foreign policy views are in many ways the exact opposite of Trump's, and who – rumor has it – may be on the way out. There are indications that, despite recent expressions of support for McMaster, the President has clashed with him repeatedly: Eli Lake reports that Trump "screamed" at his National Security Advisor for calling his South Korean counterpart after Trump said Seoul would have to pay for the THAAD antimissile defense system.
