Elon Musk of Nazi-salute fame slammed critics who have called out his white supremacist dog-whistles Saturday. "It's a relentless propaganda campaign," he said in a teased clip of an interview with Laura Trump for Fox News due to air later on Saturday. "They really are trying on every angle to get me." Musk drew widespread condemnation for giving a "Roman salute""raising his right arm in the same manner as members of the Nazi Party"while addressing the crowds at a GOP rally in January. "If they could press a button and kill me in reality, they would press that button immediately," he added. "But since I'm a little difficult to kill, they're doing character assassination instead."
