Who is Valerie Jarrett?

Jarrett’s official title — senior adviser and assistant to the president for intergovernmental affairs and public engagement — doesn’t begin to do justice to her unrivaled status in the White House. She is Ground Zero in the Obama operation — the first couple’s first friend and consigliere, the last person to leave the Oval Office after meetings, and the only White House official who dines with the first family in their private quarters at night.

“Valerie is the quintessential insider,” one of her longtime friends told me during an interview for my book, The Amateur: Barack Obama in the White House. “She functions as the eyes, ears, and nose of the president and first lady. She tells them who’s saying what about who, who’s loyal and who’s not. She advises them about who they should see when they visit a city or a foreign country. She determines who gets invited to the White House and who is left out in the cold.”

In the White House pecking order, Jarrett has more clout than the president’s chief of staff. During the savage internecine warfare between Jarrett and Obama’s first two chiefs of staff — Rahm Emanuel and Bill Daley — Obama sided most of the time with Jarrett, a classic limousine liberal who believes that Obama was elected president in order to engineer social change. Ultimately, Jarrett emasculated Emanuel and Daley and forced them from their jobs.
