Stephen Miller, a former senior adviser to President Donald Trump, vowed "vengeance" on behalf of conservative activist Charlie Kirk following Kirk's murder, remarks that have intensified an already volatile national conversation about political violence and the rhetoric surrounding it. Miller's comments, made publicly in the wake of the killing, were echoed by Vice President J.D. Vance, who used the podcast once hosted by Kirk to urge listeners to "make trouble" for people who he said were celebrating the activist's death, according to reporting by NBC News.
