The Washington Post: State Department Braces for Bolton’s Return

"He’ll work to put loyalists in key vantage points and marginalize those he distrusts,' Matthew Waxman, a former colleague of Bolton’s in the George W. Bush administration, wrote in a recent Lawfare column. 

When it comes to installing allies, Tillerson has left Pompeo and Bolton with ample opportunities, given his failure to put his own political appointees in place. Eight of the top 10 State Department jobs are vacant, and some of the people Tillerson managed to get nominated, such as Susan Thornton and Eric Ueland, could have their nominations pulled."
