Sources: Iran-Contra operative linked to questionable spy program

A former high-ranking CIA official who was involved in the Iran-Contra scandal has worked on an alleged ad hoc spy program that the Pentagon is investigating, CNN has learned. Duane "Dewey" Clarridge -- who was pardoned for his alleged role in the Reagan-era scandal by President George H. W. Bush in the waning hours of his presidency in 1992 -- is using contacts in Afghanistan and Pakistan to obtain information for the Pentagon, according to former government officials familiar with the current program. They declined to be named because of the sensitivity of the issue. The Pentagon has launched an assessment of the roles of at least three contractor companies with more than $20 million in contracts, according to Pentagon officials
