Larry Pratt has been making the rounds criticizing any new laws aimed at addressing gun violence and today appeared on Crosstalk with Vic Eliason to argue that President Obama should be impeached if he signs any executive order regarding gun policy. But Pratt, the head of Gun Owners for America, didn’t say what an executive order would entail, and executive orders have been used by Presidents Bush (41) and Clinton in the past to prohibit the import of certain assault weapons. He told one caller that any executive order would be unconstitutional and merit impeachment.
