Lawyers for a former aide to Vice President Dick Cheney have issued subpoenas to The New York Timesand one of its former reporters to provide information in his obstruction of justice case.
Lewis "Scooter" Libby, Cheney's former chief of staff, has pleaded not guilty to five counts of perjury, making a false statement and obstruction of justice over leaks about the identity of a CIA operative.
Former NYT reporter Judith Miller testified before the grand jury after serving 85 days in jail to protect a source of the disclosure who was later identified as Libby. She left the paper in November.
The subpoenas from Libby's lawyers request Miller's notes and other materials.
Court papers released in February show that Libby was authorized to disclose classified information to reporters in an effort to counteract a charge by diplomat Joe Wilson that the Bush administration twisted intelligence on Iraq to justify the 2003 invasion of the country.
Libby's charges stem from the leak of the identity of Wilson's wife, Valerie Plame, which effectively ended her career at the CIA.
