Libby to testify at CIA leak trial
US vice president Dick Cheney's former chief of staff Lewis Libby plans to testify at his impending trial to tell jurors that he never lied to investigators in the CIA leak case, according to his defence lawyers.
Mr Libby is charged with perjury, obstruction and lying to the FBI about his conversations in 2003 with reporters about CIA officer Valerie Plame's job.
Plame believes White House aides revealed her CIA status as retribution for her husband's accusation that the Bush administration twisted pre-war intelligence to exaggerate the Iraqi threat.
Libby plans to testify about President George Bush's daily terrorism briefings and other classified information to convince jurors that he had more important things on his mind and did not remember his discussions with the press, lawyers say in court papers.
