The lawyer for outed CIA operative Valerie Plame is vowing to force Vice President Dick Cheney, ex-chief of staff Lewis “Scooter” Libby and presidential adviser Karl Rove to testify in Plame’s civil lawsuit against them. Plame filed suit last month accusing the three of conspiring to end her career and putting her and her family at risk. She was outed as a CIA operative shortly after her husband Ambassador Joseph Wilson went public with findings challenging one of the Bush administration’s pre-war claims on Iraqi weapons. Plame’s attorney, Joseph Cotchett says he will invoke a 1997 Supreme Court ruling in Paula Jones’ sexual harassment case against President Bill Clinton. According to Cotchett, the ruling establishes a precedent that would grant the accused White House officials immunity only if they could prove they were acting on government business when they leaked Plame’s name to the media.
