I'm assuming he didn't tell Kerry, because if Kerry knew this and kept him on board - Kerry's toast for lack of judgment.
If "Hillary" is behind it it will be spun as a Kerry operation.
Democrats schooling Dean on foreign policy
And in the days since, Dean has announced a foreign policy team filled with big names, from Anthony Lake, who was national security adviser under Clinton, to retired general Joseph Hoar, a top commander in the 1991 Gulf War.
Not everyone who has tutored Dean has endorsed him or even agrees with him; Albright, Clinton, and other pillars of the Democratic establishment, such as former national security adviser Samuel R. Berger, say they are talking to all candidates who ask.
But the tutorials apparently serve a dual purpose: Dean, who as governor of Vermont had little official contact with other nations except Canada, is getting a grounding in foreign policy and an opportunity to cement his credentials among mainstream Democratic thinkers. And the Democratic establishment is getting an opportunity to influence a key aspect of the man who could be their party's nominee, but whose unequivocal declarations have sometimes alarmed the party's standard-bearers.
