The Trump administration has a personnel problem. Multiple government agencies are in a state of staffing gridlock, with cabinet secretaries having their chosen employees routinely returned by the White House's Office of Personnel Management. Steve Mnuchin at Treasury, Rex Tillerson at State, General Mattis at Defense, it's a problem across the Cabinet.
Why this matters: The failure to fill lower-level staff directly impacts the ability of government to function. Career people are working away, but senior political appointees lack their own staff. They're less effective — and operating in a climate of distrust — until they've got their team around them.
