Libby is the highest-ranking White House official to be convicted of a felony since the Iran-Contra scandal of the mid-1980s. The conviction focused renewed attention on the Bush administration's much-criticized handling of weapons of mass destruction intelligence in the run-up to the Iraq war.
The verdict culminated a nearly four-year investigation into how CIA official Valerie Plame's name was leaked to reporters in 2003. The trial revealed how top members of the Bush administration were eager to discredit Plame's husband, former Ambassador Joseph Wilson, who accused the administration of doctoring prewar intelligence on Iraq.
Libby, who was once Cheney's most trusted adviser and an assistant to Mr. Bush, was expressionless as the jury verdict was announced on the 10th day of deliberations. His wife choked out a sob and sank her head.
"I am very disappointed with the verdict," Vice President Cheney said in a written statement. "I am saddened for Scooter and his family. As I have said before, Scooter has served our nation tirelessly and with great distinction through many years of public service."
He faces up to 30 years in prison when he is sentenced June 5, but under federal sentencing guidelines is likely to face far less. Defense attorneys immediately promised to ask for a new trial or appeal the conviction.
"We have every confidence Mr. Libby ultimately will be vindicated," defense attorney Theodore Wells told a throng of reporters. "We believe Mr. Libby is totally innocent and that he didn't do anything wrong."
Libby did not speak to reporters.
Special Prosecutor Patrick Fitzgerald, who has led the leak investigation, said no additional charges would be filed. That means nobody will be charged with the leak and Libby, who was not the source for the original column outing Plame, will be the only one to face trial.
"The results are actually sad," Fitzgerald said. "It's sad that we had a situation where a high-level official person who worked in the office of the vice president obstructed justice and lied under oath. We wish that it had not happened, but it did."
The verdict is a political blow to the administration, reports CBS News White House correspondent Mark Knoller, and so great was the interest in the outcome of the trial that President Bush watched live reports of it on TV in the Oval Office.In fall 2005, late "60 Minutes" correspondent Ed Bradley reported on the harm Valerie Plame's outing had done to her and the CIA.
A spokeswoman said Mr. Bush accepted the jury's verdict and was saddened for Libby and his family — but because it's still an ongoing criminal proceeding the White House declined further comment.
Democrats reacted quickly to the verdict.
"I welcome the jury's verdict," said Senate Majority Leader Harry Reid in a statement. "It's about time someone in the Bush administration has been held accountable for the campaign to manipulate intelligence and discredit war critics."
Reid called on President Bush to pledge "not to pardon Libby for his criminal conduct."
