Andrea Mitchell reporting for NBC News:

Two Obama advisers have told NBC News that Hillary Clinton is under consideration to be secretary of state. Would she be interested? Those who know Clinton say possibly. But her office says that any decisions about the transition are up to the president-elect and his team.

Clinton was seen taking a flight to Chicago today, but an adviser says it was on personal business. It is unknown whether she had any meeting or conversation with Obama while there.

Other Democrats known to want the State Department post are Sen. John Kerry and Gov. Bill Richardson. A possible compromise choice would be former Sen. Tom Daschle.

UPDATE: Al Kamen has it too.

... OK. I think I see the game here. Politico's Mike Allen explains what is going on:

Several Obama transition advisers are strongly advocating Sen. Hillary Rodham Clinton (D-N.Y.) for secretary of State, a move that would create the ultimate “Team of Rivals” cabinet, according to officials involved in the discussions.

President-elect Obama has narrowed the possibilities for secretary of State and Clinton is among those being strongly considered, the officials said. Some even call her the favorite.

It is not known what Obama himself thinks of the idea.
