An update on the tiff between Jonathan Alter and Roger Ailes.

Using his other "publication," the Huffington Post, Alter has posted his response to Ailes' bitter letter of last week: "Perhaps you did not notice, but my Watergate column was satirical." Then he starts landing his punches:

"I'm glad you have not been caught in any recent mistakes and--as I mentioned in my post--you employ many fine journalists. But one reason your coverage may make fewer mistakes is that you do so little of the investigative reporting of business and government that is necessary for an informed citizenry. Fox's list of scoops on matters of public importance is extremely short. Perhaps when your network does less regurgitation and repackaging of news--and more original investigative reporting--you will be a little less hasty to cast stones."

What's the next step?
