The war on Gary Webb is covered at The Intercept.
The CIA watched these developments closely, collaborating where it could with outlets who wanted to challenge Webb’s reporting. Media inquiries had started almost immediately following the publication of “Dark Alliance,” and Dujmovic in “Managing a Nightmare” cites the CIA’s success in discouraging “one major news affiliate” from covering the [Contra Cocaine] story.
…Contras themselves knowingly received financial and material assistance from drug traffickers. In each case, one or another agency of the U.S. government had information regarding the involvement either while it was occurring, or immediately thereafter.”
The chief of the CIA’s Central America Task Force was also quoted as saying, “With respect to (drug trafficking) by the Resistance Forces…it is not a couple of people. It is a lot of people.”
