Ms Jarrett is an employee of the US government, a public servant. Let us not dismiss that fact. Whether her status ("prominence") or her functions, regardless of the advice and consent of the senate or the "pleasure of the president" condemns the trust vest in the office that she attends is question provoked by rootless2's observation --indictment, I'd say-- of  so-called left bank political analyses:

The actually powerful figures who surround the President, such as Valerie Jarret, are ignored - not surprising that a black woman disappears from view....

If you look at the articles, you'll see it's worse than that - although to be fair, Hilda Solis might be ignored because she's in the Department of Labor not because she's a latina.

Diversity is the key to economic and political evolution.
