McDonnell is taking flak on the left for the diversity of the people sitting behind him tonight. See Daily Kos here, for instance. I’m told that in the offending screen-shot:

The white woman is Janet Polarek — Secretary of the Commonwealth
Above her is Jim Cheng — Secretary of Commerce and Trade
The soldier is Staff Sargeant Robert Tenpenny, who served with Jeanine McDonnell in Iraq.
Above him is Lisa Hick-Thomas — Secretary of Administration
The Secretaries are all McDonnell Cabinet members.
