Keith Olbermann, who did the Nazi salute with an O'Reilly mask covering his face, has responded to FOX News' Roger Ailes remark that the MSNBC host's action was over the line.

Unsurprisingly, Olbermann's response was made available to TVNewser:

"'Over the line?' Where was Roger when O'Reilly defended the Nazi SS stormtroopers from Malmedy in World War II? The SS shot 84 American POW's there in 1944, and three different times in the last year, Bill called has called those dead Americans war criminals. I guess there is no line at Fox News."
