I have never read that his espionage went that far, and it is never mentioned in stories about him.
If you google, I think you'll find reports that this is exactly what Caspar Weinberger was royally angry about -- that the info went from Pollard to his handlers and eventually was sold to Soviets. There are reports out there to this effect. Certainly SOMETHING persuaded Weinberger and the intelligence community to throw the book at this guy - - giving him, as his supporters point out, a sentence way beyond normal for what Pollard claims to have done.
