The New York Times has a profile of Valerie Jarrett, an aide to President Obama:
she can also be imperious — at one event ordering a drink from a four-star general she mistook for a waiter — and attached to the trappings of power in a way some in the White House consider unseemly for a member of the staff.
A case in point is her full-time Secret Service detail. The White House refuses to disclose the number of agents or their cost, citing security concerns. But the appearance so worried some aides that two were dispatched to urge her to give the detail up.
She listened politely, one said, but the agents stayed.
