Glenn Greenwald has been waging his own little war against Time columnist Joe Klein for more than a week now owing to what Greenwald says was a "factually false" description of the FISA legislation in the House in Klein's latest piece.

According to Greenwald, the error lies in Klein's claim that the bill "require[s] the surveillance of every foreign-terrorist target's calls to be approved by the FISA court." Klein responded to Greenwald here, but apparently didn't go far enough to satisfy his critics, and it's been back and forth for a few days now. Klein allowed that he might have misinterpreted the Democratic position, and "If I did, a correction will appear in the print magazine next week. This only got him into more trouble with his friends on the left, ultimately leading to this gem from Klein:

I have neither the time nor legal background to figure out who's right.

Klein, not content to stop digging after five updates (remind you of anyone?), would later add after that sentence, "(ADD: about this minor detail of a bill that will never find its way out of the Congress)."

Kos himself has since joined the pile on, here, and now Greenwald has kicked it up a notch, teaming up with the "tenacious" Jane Hamsher to go after Klein's editor.

The whole thing is a bit ridiculous, but, like a battle between the Giants and Cowboys, it's fun to watch and root for injuries.
