Following up on a Crimson report (excellent catch, Crimson), the Globe reports that Goldman Sachs knew it was screwing Harvard.

A Goldman Sachs e-mail from February 2007 acknowledged that a large trade in complex mortgage-related securities would be “good for us’’ but bad for several customers, including Harvard University.

In a Feb. 14, 2007, message detailing the decline of high-risk subprime mortgages, Goldman executive Daniel Sparks wrote to colleagues: “That is good for us position-wise, bad for accounts who wrote that protection,’’ citing Harvard and three others.

The plot thickens.

Couple things.

One, Goldman Sachs didn’t hesitate to screw a counterparty on whose board sat one of its former partners (not to mention the former US Treasury secretary).

Two, that partner—Bob Rubin, of course—either wasn’t in the loop on this deal or didn’t understand it or was just wrong.

From his steadfast support of Larry Summers, to his part in negotiating Summers’ obscene golden parachute, to fiscal irresponsibility such as the above, to his demonstrated lack of interest in the work of the Corporation, Rubin has been a disastrous member of the Harvard board. (That’s not even mentioning his disastrous tenure at Citigroup and his absurd nine-figure compensation.)

So why is he still on it?
