The NY Times sounds the alarm:

WASHINGTON — Of all the State Department employees who might have been vulnerable in the staff reductions that Secretary of State Rex W. Tillerson has initiated as he reshapes the department, the one person who seemed least likely to be a target was the chief of security, Bill A. Miller.

Republicans pilloried Hillary Clinton for what they claimed was her inadequate attention to security as secretary of state in the months before the deadly 2012 attacks in Benghazi, Libya. Congress even passed legislation mandating that the department’s top security official have unrestricted access to the secretary of state.

But in his first nine months in office, Mr. Tillerson turned down repeated and sometimes urgent requests from the department’s security staff to brief him, according to several former top officials in the Bureau of Diplomatic Security. Finally, Mr. Miller, the acting assistant secretary for diplomatic security, was forced to cite the law’s requirement that he be allowed to speak to Mr. Tillerson.

Mr. Miller got just five minutes with the secretary of state, the former officials said. Afterward, Mr. Miller, a career Foreign Service officer, was pushed out, joining a parade of dismissals and early retirements that has decimated the State Department’s senior ranks. Mr. Miller declined to comment.

The departures mark a new stage in the broken and increasingly contentious relationship between Mr. Tillerson and much of his department’s work force. By last spring, interviews at the time suggested, the guarded optimism that greeted his arrival had given way to concern among diplomats about his aloofness and lack of communication. By the summer, the secretary’s focus on efficiency and reorganization over policy provoked off-the-record anger

Now the estrangement is in the open, as diplomats going out the door make their feelings known and members of Congress raise questions about the impact of their leaving.

In a letter to Mr. Tillerson last week, Democratic members of the House Foreign Relations Committee, citing what they said was “the exodus of more than 100 senior Foreign Service officers from the State Department since January,” expressed concern about “what appears to be the intentional hollowing-out of our senior diplomatic ranks.”

Senator John McCain, Republican of Arizona, and Senator Jeanne Shaheen, Democrat of New Hampshire, sent a similar letter, telling Mr. Tillerson that “America’s diplomatic power is being weakened internally as complex global crises are growing externally.”
