Leaker Edward Snowden accused the National Security Agency of targeting reporters who wrote critically about the government after the 9/11 attacks and warned it was “unforgivably reckless” for journalists to use unencrypted email messages when discussing sensitive matters.

Snowden said in an interview with the New York Times Magazine published Tuesday that he came to trust Laura Poitras, the documentary filmmaker who, along with Guardian reporter Glenn Greenwald, helped report his disclosure of secret surveillance programs, because she herself had been targeted by the NSA.

“Laura and [Guardian reporter] Glenn [Greenwald] are among the few who reported fearlessly on controversial topics throughout this period, even in the face of withering personal criticism, and resulted in Laura specifically becoming targeted by the very programs involved in the recent disclosures,” Snowden said for the article, a profile of Poitras.
