The CIA has launched an investigation of its own employees over a dispute with a Senate panel probing the agency’s torture and rendition program. Members of the Senate Intelligence Committee say CIA officials illegally monitored their staffers’ work as they compiled the panel’s exhaustive probe on CIA torture. The report has yet to be declassified but reportedly documents extensive abuses and a cover-up by CIA officials to Congress. Details are under wraps, but the new probe reportedly began after the CIA took what Democratic Senator Mark Udall called an “unprecedented action” against his committee.
