Vice President's Chief of Staff Indicted in CIA Leak Investigation

Vice President Dick Cheney's chief of staff, Lewis Libby, has been charged with five criminal counts as part of a grand jury investigation into who leaked the identity of a covert CIA operative.

Mr. Libby resigned after the charges were announced Friday, and said in a statement he is confident he will be exonerated. The vice president said he accepted the resignation with deep regret.

Mr. Libby was indicted on charges of obstruction of justice, perjury before the grand jury and making false statements to FBI agents. He was not charged with knowingly revealing the identity of CIA operative Valerie Plame, the charge that touched off the inquiry.

The special prosecutor in the case, Patrick Fitzgerald, said it is especially important for witnesses before the grand jury to tell the complete truth, particularly when it involves national security issues.

Mr. Fitzgerald also said the investigation is not over. The lawyer for President Bush's top political adviser Karl Rove, says Mr. Rove remains under investigation.

Mr. Libby faces up to 30 years in prison and more than a million dollars in fines if convicted on all counts.
