Emanuel offered White House Chief of Staff

November 5, 2008 Emanuel, a knowledgeable source tells ABC News, has not yet given his answer. The sharp-tongued, sharp-elbowed, keenly intelligent veteran of the Clinton White House is said to have ambitions to some day be Speaker of the House. But he also has a keen sense of "duty."

Today on "Good Morning America" ABC's George Stephanopoulos reported Obama likes the fact that Emanuel "knows policy, knows politics, knows Capitol Hill" and has told associates that Emanuel will "have his back."

There is a tentative plan to announce Obama's chief of staff this week.
