A few weeks after he took over the investigation into the leak of covert CIA agent Valerie Plame Wilson in early 2004, Special Prosecutor Patrick Fitzgerald had already become suspicious that Karl Rove and Vice President Cheney's then-chief of staff I. Lewis "Scooter" Libby were hindering his investigation. In late January 2004, Fitzgerald sent a letter to his boss, then acting Attorney General James Comey, seeking confirmation that he had the authority to investigate and prosecute individuals for additional crimes, including obstruction of justice, perjury, and destroying evidence. The leak investigation had been centered up to that point on an obscure law making it a felony for any government official to knowingly disclose the identity of an undercover CIA officer. |
