It seems, based on a few conservative Trump supporting websites that H.R. McMaster needs to be purged from president Trump's team, rather than being the purger-in-chief himself.
Via the Free Beacon:
An ongoing staffing purge being conducted by White House National Security Adviser H.R. McMaster has thrown the West Wing into chaos, according to more than half a dozen Trump administration insiders who told the Washington Free Beacon that McMaster has been targeting long-time Trump loyalists who were clashing with career government staffers and holdovers from the Obama administration.The purge is part of a larger drama unfolding inside the administration, between veteran Trump staffers committed to the president's campaign vision of "draining the swamp"‘ in Washington and entrenched bureaucracies seeking to maintain control over policy decision-making, according to these sources, who said that many of these actions against his supporters are being conducted without Trump's knowledge.
And via Gateway Pundit:
National Security Advisor H.R. McMaster is leading the globalist purge of pro-Trump loyalists from the White House. After firing a number of ‘America First’ orientated officials, reports have surfaced that the motive behind firing Rich Higgins, Derek Harvey, and Ezra Cohen-Watnick may run deeper than just removing out Trump allies. A new report reveals McMaster may have purged the officials because they were also pro-Israel. McMaster is reportedly deeply hostile towards Israel and even banned Israeli prime minister Benjamin Netanyahu from accompanying President Trump to the Western Wall.
National Security Advisor H.R McMaster has been in the news a great deal this week as he continues his purge of Trump loyalists. Now there are reports McMaster might be shipped off to Afghanistan to oversee the war. The news also comes amid reports McMaster was caught leaking internal White House politics to now former Acting FBI Head Andy McCabe.
For those of us for whom McMaster wasn't really on the radar, it seems rather suddenly, that he needs to go. It doesn't help his case when he is also suddenly being defended by the likes of Slate. For conservatives that defense should be the kiss of death for McMaster's executive branch career.
