According to a story on Huffington Post, Obama Names Valerie Jarrett Senior White House Advisor. The story on HuffPo is rather brief but the links in the story and in the comments more than make up for the brevity.

Particularly enlightening is the DailyKos article So just who is Valerie Jarrett?

The DailyKos article had a link to an interview with Jarrett conducted by Katie Kouric.

The intellectual depth that Obama and his advisors would bring to the executive branch is one of the things that attracted me to Obama in the beginning. So far there have been few, if any, disappointments along these lines.
