John Kiriakou

As pundits debate how Barack Obama will tackle guns, climate change, immigration, and the debt ceiling in his newly inaugurated second term, press freedom advocates are left questioning how the U.S. president will handle another, no-less-controversial issue: the treatment of whistleblowers and officials who leak information to the media.

Few cases better underscore the need for digital security among journalists. On Tuesday, ex-CIA officer John Kiriakou pleaded guilty to leaking the identity of another CIA operative to Matthew Cole, a journalist formerly with an ABC News investigative team. In a 2007 interview with ABC, Kiriakou became the first CIA official to confirm that waterboarding had been used on Al-Qaeda suspects.
