As reported by Wayne Washington of the Boston Globe in an article titled, “US Begins criminal probe of CIA leak,” Senator Dick Durbin raised the question on the floor of the U.S. Senate in the context of the Justice Department investigation into who leaked Valerie Plame’s identity as a CIA employee:
Speaking on the Senate floor, Senator Richard J. Durbin, Democrat of Illinois, described how FBI agents, at the behest of the Bush administration, asked that he submit to a lie detector test to help them uncover who leaked classified information that had been provided to the Senate Intelligence Committee, of which Durbin is a member.
He argued that the Justice Department won’t be as aggressive in pursuing White House officials. “Is . . . John Ashcroft willing to ask Karl Rove to submit to a polygraph?” Durbin asked.
