The honeymoon seems to be ending between retired Gen. James N. Mattis and Donald Trump’s transition team amid an increasingly acrimonious dispute over who will get top jobs in the Defense Department — and who gets to make those decisions.

With only two weeks left before Inauguration Day and days before Mattis’s Senate confirmation hearing, most major Pentagon civilian positions remain unfilled. Behind the scenes, Mattis has been rejecting large numbers of candidates offered by the transition team for several top posts, two sources close to the transition said. The dispute over personnel appointments is contributing to a tenser relationship between Mattis and the transition officials, which could set the stage for turf wars between the Pentagon and the White House in the coming Trump administration.
