'A former key White House official, Lewis Libby, has been found guilty of obstruction of justice and perjury.
Libby, ex-chief of staff to Vice-President Dick Cheney, faces a prison term of up to 25 years. He will be sentenced in June.
He was accused of lying to the FBI and a grand jury over revelations about CIA agent Valerie Plame's identity.
Libby's lawyer said they were "very disappointed" at the verdict, and would ask for a new trial, or would appeal.'
