(Minneapolis, MN)  —  Senator Amy Klobuchar is calling the attack on House Speaker Nancy Pelosi’s husband “vicious.”  Appearing on NBC’s Meet the Press, the Minnesota Democrat said that Pelosi has been vilified for years, and Friday’s attack that left Paul Pelosi with a skull fracture is an example of the violence spreading through the political system.  Senator Klobuchar also suggested that extending security to the families of top U.S. officials should be “strongly considered.”
