My new piece at The Nation. UPDATE #1: Kevin Drum at Mother Jones asks, what's on the 35 or so PRISM slides that neither the Post nor The Guardian chose to publish, despite Snowden's request/demand? He wants Greenwald and Gellman to desctribe why not published and maybe, generally, what they pertain to. I would add that I doubt that it was the two reporters' call.
UPDATE #2 Mike Calderone at Huff Post has just written this valuable untangling,
with film-make Laura Poitras, it turns out, playing perhaps THE key role. Snowden, he
explains, first approached Greenwald months ago but Glenn was stymied
by tech issues and didn't know what the leak entailed. Poitras met
Greenwald later and told him that Snowden had told her details and this
sparked all that followed. As for Gellman: It appears true that
Snowden did go to him first with PRISM, and then to Greenwald. But
Greenwald objects to Gellman suggesting that Glenn was the second choice
all along, when in fact he had gotten the first leak...first.
