President Donald Trump’s counter-terrorism adviser Sebastian Gorka has resigned. Gorka, seen as an outspoken and combative defender of President Donald Trump’s national security agenda, left his position willingly. According to CNN, the news, which came late on Friday, was widely expected in the West Wing, which has now seen high-profile departures on successive Fridays for several weeks. Gorka was one of Trump’s most prominent cheerleaders, frequently hitting the airwaves to defend the President’s policies and public statements. But his role outside of television hits was unclear. He did not play a major policy-making role, according to administration officials, and was not a member of the National Security Council. A White House official told CNN that the security expert submitted his resignation to retired Gen. John Kelly, the White House chief of staff, on Friday. The official said it had become clear that Gorka would not be allowed to have a meaningful role going forward. But a separate White House official disputed that he resigned. “Sebastian did not resign, but I can confirm he is no longer with the White House,” the second White House official said, according to a statement given to reporters. Kelly, who assumed the chief of staff role in late July, has been conducting a review of the West Wing that includes assessing individual staffers’ portfolios.
