Stephen Miller spoke at FBI training on domestic terrorism, sources say

Stephen Miller, White House homeland security adviser, delivered a speech at a counterterrorism training conference at FBI headquarters just over a week ago, days before prosecutors charged a man for making threatening calls and texts to his wife, Katie Miller, according to multiple sources. Former Justice Department officials found Miller's visit unusual and contrary to longstanding norms of separating federal criminal investigations from political influence.

The administration and FBI maintained that his participation was appropriate, citing his role in the White House and their focus on combating political violence. Miller informed the agents that President Trump's initiative to counter domestic terrorism was a personal matter to him, referencing the 2025 assassination of his friend, Turning Point USA founder Charlie Kirk.

He emphasized the necessity for federal law enforcement to be more proactive in investigating threats, regardless of the target, and stressed that no case was too small. The FBI official stated that Miller's remarks reflected a broader effort by federal law enforcement to prevent mass-casualty events by intensifying investigations into threat and harassment cases.

The training session, attended by FBI assistant special agents specializing in counterterrorism and officials from other law enforcement agencies, was appropriate for Miller's position as homeland security adviser, tasked with executing the president's executive order on countering domestic terrorism and political violence.
