In his resignation letter, Gorka said that he felt as though "the individuals who most embodied and represented the policies that will 'Make America Great Again'" were being "systematically removed" from the administration. Specifically, Gorka cited Trump's speech on Monday outlining his strategy in Afghanistan--and its lack of mentioning radical Islamic terrorism--as proof of this and as a reason why he is stepping down.

“Regrettably, outside of yourself, the individuals who most embodied and represented the policies that will ‘Make America Great Again,’ have been internally countered, systematically removed, or undermined in recent months. This was made patently obvious as I read the text of your speech on Afghanistan this week… “The fact that those who drafted and approved the speech removed any mention of Radical Islam or radical Islamic terrorism proves that a crucial element of your presidential campaign has been lost… “Just as worrying, when discussing our future actions in the region, the speech listed operational objectives without ever defining the strategic victory conditions we are fighting for. This omission should seriously disturb any national security professional, and any American who is unsatisfied with the last 16 years of disastrous policy decisions which have led to thousands of Americans killed and trillions of taxpayer dollars spent in ways that have not brought security or victory.”

Despite this, Gorka said that he believes that Trump's election was a significant event, and he hopes that he will listen to the American people who elected him in the first place.
