As the FBI investigates the onslaught of threats to politicians in 2009, new details have emerged on the scary new trend that has required a $2.7 million increase in funding for the necessary police work. One caller left a voicemail for Rep. Heath Shuler (D-NC) saying, “I voted for you. If you vote for that stimulus package, I’m gonna kill you. Simple as that,” which he later described as an attempt to “work the political scene.” Another who threatened Sen. Debbie Stabenow (D-MI) cited fears that the government would silence his favorite radio hosts, Sean Hannity and Rush Limbaugh. Though most reported threats are not considered serious, the cases continue to stack up and show no signs of stopping: In the first few months of 2010, threats to Congress tripled.
