In consultation with confidants inside and outside the administration, Scaramucci has begun undertaking an audit of the White House’s dozens of press and communications staffers. He is meeting one-on-one with aides in an effort to understand each person’s contributions and weed out those he determines are not working hard enough to defend the president through the crises besieging the White House, according to several of the officials, who spoke on the condition of anonymity to discuss sensitive internal issues.

The potential shake-up has exacerbated long-simmering tensions between Scaramucci and chief of staff Reince Priebus, according to people familiar with the dynamic, despite the outward, if forced, public displays of unity between the two men.

Scaramucci has long complained to associates that some White House staffers have been more focused on managing the image of Priebus than on defending Trump and promoting his agenda. An informal list of names, including several officials who previously worked under Priebus and Spicer at the Republican National Committee, has been circulating among Scaramucci allies as those whose jobs may be in jeopardy.
