Craig Deare, whom Trump appointed a month ago to head the National Security Council's Western Hemisphere division, was on Friday escorted out of the Executive Office Building, where he worked in Washington.

A senior White House official confirmed that Deare is no longer working at the NSC and has returned to the position he previously held at the National Defense University. The official spoke on condition of anonymity to discuss an incident not otherwise made public, and provided no further details.

But current and former administration officials say Deare's termination was linked to remarks he made Thursday at a private talk at the Wilson Center, a Washington think tank. The officials spoke on condition of anonymity because they were not authorized to discuss the matter.
