A Georgia Republican is criticizing Pima County Sheriff Clarence Dupnik (DOOP'-nik) for linking Saturday's shooting in Arizona with overheated political rhetoric.
Rep. Jack Kingston said in an interview Monday there is no evidence the shooting was politically motivated. He says it simply looks like the work of a deranged gunman. He called the sheriff's comments "irresponsible."
Kingston also questions whether Dupnik might have missed signs that Jared Loughner would engage in violence given Loughner's history of suspicious behavior.
The 10-term congressman says leaders and citizens should tone down negative rhetoric. But he cautions against new congressional security measures and says fiery discourse is healthy for democracy.
Dupnik suggested over the weekend that the vitriol in modern politics may have played a role in the tragedy.
