Longstanding friction between U.S. President Donald Trump and two top aides, the National Security Adviser and the Chief of Staff, has grown to a point that either or both might quit soon, four senior administration officials said.
Both H.R. McMaster and John Kelly are military men considered by U.S. political observers as moderating influences on the president by imposing a routine on the White House. They have also convinced Trump of the importance of international alliances, particularly NATO, which he has criticized as not equally sharing its burdens with the United States.
However, all the officials were quick to add that the tensions could blow over, at least for now, as have previous episodes of discord between the president and other top officials who have fallen out of favor, including Secretary of State Rex Tillerson and Attorney General Jeff Sessions.
