Okay this is from WSWS but I think it is a good recap of Silberman's career.
http://www.wsws.org/news/1998/july1998/silb-j18.shtmlThe judge who declared that Clinton was "at war with the US government" is a long-time political operative in the right-wing of the Republican Party. In 1980 Silberman served as a Reagan campaign aide carrying out some of the most delicate and politically sensitive assignments. He was dubbed the Reagan-Bush campaign's "ambassador to Iran" for his behind-the-scenes contacts with the Khomeini regime.
Silberman's reward was a nomination to the Court of Appeals for Washington DC, the most political and powerful circuit court because it handles most cases involving the federal government. His most important decision on the Court of Appeals came in the case of Lt. Col. Oliver North, the principal figure in the Iran-Contra affair. Silberman and fellow justice David Sentelle, a former aide to arch-right-wing Republican Senator Jesse Helms, voided the convictions of both North and Admiral John Poindexter in 1990. Their intervention played a key role in sabotaging the investigation by Iran-Contra special prosecutor Lawrence Walsh.
Silberman's close ally Sentelle was largely responsible for the 1994 decision to remove Whitewater prosecutor Robert Fiske and replace him with the more conservative and highly partisan Republican Kenneth Starr as Independent Counsel. Sentelle chaired the three judge panel which removed Fiske and appointed Starr in his place. The other two members of the panel were retired judges who normally follow the direction of chairman. When Silberman declares that Starr alone represents the US government, he is silent on how the right-wing judge--a former colleague of Silberman's on the Circuit Court bench--came to be chosen.
The Iran-Contra investigation was being blocked by the Bush administration, which refused to permit classified CIA documents to be turned over to North and other defendants, citing "national security." This was a transparent maneuver to hamstring the prosecution, in which the White House encouraged North, Poindexter & Co. to seek the documents and then instructed the CIA to refuse them, in order to create an appealable issue.
