Not sure if this has been reported already, but...
Representative Steve Stockman's latest assault in the war on People Who Want To Take Your Guns now accuses President Obama (or his supporters) of setting up spambots to tweet him. The National Review story makes it sound as though he and other representatives are being flooded by thousands of messages.

The Hill, however, probed a bit more deeply and adds the following details: "Stockman said that in response to Obama's call for people to tweet their congressman in support of gun control legislation, he received just 16 tweets (which isn't much of a flood.) But he said all of these messages were identical, and that a closer look at them revealed that only six were from real people."

The National Review has links to two of these accounts, with no real indication of who set them up.
