It's actually a letter from Tribe to Valerie Jarrett after Obama was elected in 2008.
Read the whole thing -- it's an exercise in brown-nosing.
But, the final reply from Todd Stern may be dismissive:
Maybe we could do this and put his office in Alston.
I'm not sure what "Alston" may be. It's one of the names on a law firm with offices in DC. Or, maybe it's a location intended to put Tribe "out of the way".
Podesta may hold a grudge against Tribe because he supported Clinton over Obama in 2008.
Allston is the neighborhood across the Charles River from Cambridge, where Harvard is expanding. So I guess Stern means that if Tribe had this position, his office would be near Harvard.
