President Donald Trump has repeatedly clashed with his national security adviser, H.R. McMaster, in front of his staff, according to a column by Eli Lake at Bloomberg published Monday.

The three-star Army general increasingly is being sidelined in favor of other advisers because Trump has become “disillusioned” with him, according to Lake. Three White House officials told Lake the president was “livid” after McMaster called his South Korean counterpart to assure him that Trump’s threat to make Seoul pay for the advanced THAAD missile defense system was not official policy.

Trump also has said in front of McMaster that he is “undermining my policy,” according to two White House officials who spoke with Lake.

The White House did not immediately respond to a request for comment from Business Insider. However, Bloomberg received a statement from Trump that said: “I couldn’t be happier with H.R. He’s doing a terrific job.”

McMaster received plenty of praise when he was tapped to replace retired Lt. Gen. Michael Flynn as national security adviser. Many pundits said his strategic expertise, doctoral education, heroism during Operation Desert Storm, and respect among the rank-and-file would be good news for Trump’s National Security Council.
