I remember when this happened and was frustrated that no one looked into it at the time:
From Think Progress again:
"In 2002, Black launched an investigation into Jack Abramoff’s “secret arrangement with Superior Court officials to lobby against a court reform bill then pending in Congress.” On Nov. 18, 2002, Black issued a grand jury subpoena to the Guam Superior Court to turn over all records involving the lobbying contract with Abramoff. The administration swiftly punished Black:
A day later, the chief prosecutor, US Attorney Frederick A. Black, who had launched the investigation, was demoted. A White House news release announced that Bush was replacing Black.
The timing caught some by surprise. Despite his officially temporary status as the acting US attorney, Black had held the assignment for more than a decade."
It is amazing to me that we are beginning to extract ourselves from this mess. Given the concentration of power, in the Executive Branch of Government, over the past four years, it is a testament to our Democracy that we are getting blind justice back on track.
