From the letter:
The identity of undercover CIA operatives is supposed to be one of the most closely guarded national security secrets. There are a host of administrative requirements designed to safeguard this type of information from disclosure. Yet the trial proceedings raise questions about whether senior White House officials, including the Vice President and Senior Advisor to the President Karl Rove, complied with the requirements governing the handling of classified information. They also raise questions about whether the White House took appropriate remedial action following the leak and whether the existing requirements are sufficient to protect against future leaks. Your perspective on these matters is important.
After the verdict was announced yesterday, one juror expressed the view that former Chief of Staff to the Vice President Lewis "Scooter" Libby was only a"fall guy." This juror's views encapsulated questions that many in Congress and the public have about whether the ultimate responsibility for the outing of Ms. Wilson rests with more senior officials in the White House. This is another area where you have a unique perspective.
I recognize that as a federal prosecutor, you are constrained by the rules of grand jury secrecy. But you undoubtedly recognize that Congress has a responsibility to examine the policy and accountability questions that your investigation has raised. As a result of your investigation, you have a singular understanding of the facts and their implications that bear directly on the issues before Congress.
