Attorneys for I. Lewis "Scooter" Libby believe that NBC News holds a key to clearing him of perjury and obstruction charges in the CIA leak case.
Libby, the former chief of staff to Vice President Dick Cheney, wants a federal judge to let his lawyers question Andrea Mitchell, NBC's foreign affairs correspondent, about when she learned that the wife of an outspoken Bush administration critic worked for the CIA.
Libby is charged with lying and obstructing the investigation into the leak of CIA operative Valerie Plame's identity. Prosecutors rested their case Thursday and Libby is set to begin calling witnesses Monday
A key dispute in the case involves Mitchell's NBC colleague, Tim Russert. Libby says Russert told him in July 2003 that "all the reporters know" Plame worked for the CIA. Russert said that never happened because he didn't know who Plame was at the time.
