WASHINGTON -- A Senate Sergeant-at-Arms investigation into a dispute between the CIA and the Senate Intelligence Committee has ended without firm conclusions after failing to examine crucial computer records that investigators said were erased by the agency, sources familiar with the inquiry told The Huffington Post. CIA officials, however, told The Huffington Post that the computer records not only exist, but were provided to Senate investigators, leaving the dispute's final inquiry shrouded in questions. The probe by the Senate’s chief law enforcer was the last running investigation into competing allegations of wrongdoing lobbed between the CIA and its oversight committee.
