Karl plays for time. AP: "Federal prosecutors have accepted an offer from presidential adviser Karl Rove to give 11th hour testimony in the case of a CIA officer's leaked identity but have warned they cannot guarantee he won't be indicted, according to people directly familiar with the investigation. The persons, who spoke only on condition of anonymity because of grand jury secrecy, said Special Prosecutor Patrick Fitzgerald has not made any decision yet on whether to file criminal charges against the longtime confidant of President Bush or others."
