President Donald Trump is escalating his attack on progressive groups following the assassination of right-wing activist Charlie Kirk and a deadly shooting that targeted an immigration jail in Dallas. White House officials have repeatedly blamed Democrats and left-wing groups for contributing to political violence, but investigative reporter Ken Klippenstein says the motivations of people who commit such acts are often more complicated. Klippenstein has reported on the backgrounds of Kirk’s accused killer and the gunman who targeted the Dallas ICE facility, and says friends described both young men as somewhat isolated and largely uninterested in partisan politics. “That was perhaps the most normal thing about these two shooters, that they were disengaged with politics,” he says.
