CBS News reports:

The FBI believes it has “solid” evidence that the suspected mole supplied Israel with classified materials that include secret White House policy deliberations on Iran. At the heart of the investigation are two people who work at The American Israel Public Affairs Committee (AIPAC), a powerful pro-Israel lobby in Washington. The FBI investigation, headed up by Dave Szady, has involved wiretaps, undercover surveillance and photography that CBS News was told document the passing of classified information from the mole, to the men at AIPAC, and on to the Israelis. […] The case raises another concern among investigators: Did Israel also use the analyst to try to influence U.S. policy on the war in Iraq?

From The Forward in 2003:

“A budding coalition of conservative hawks, Jewish organizations and Iranian monarchists is pressing the White House to step up American efforts to bring about regime change in Iran.”

This doesn’t seem like it will do much good for Jonathan Pollard’s case.
