WASHINGTON — Senior White House aide Stephen Miller vowed an aggressive federal campaign against what he called “violent radical leftist groups,” saying the government will use all available resources to identify and dismantle those networks “in Charlie’s name.” Miller made the pledge while speaking on a program honoring the late conservative activist Charlie Kirk.

Miller said the effort would draw on the Department of Justice, Homeland Security and other federal tools to “identify, disrupt, dismantle, and destroy these networks,” framing the move as a response to a climate of political hostility he and other officials have blamed for Kirk’s killing. His comments were widely reported by national outlets and prompted immediate debate over civil-liberties and enforcement boundaries.

The White House and allied officials have argued the steps are necessary to confront organizations and groups they say foment or encourage political violence. Critics — including civil-liberties advocates and some Democrats — warned the rhetoric risks being used to suppress dissent and could lead to overreach by federal agencies without clear evidence linking the groups named to criminal acts. Reuters and international outlets have highlighted these concerns.
