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

White House homeland security adviser Stephen Miller spoke at a training conference for counterterrorism agents at FBI headquarters just over a week ago, days before prosecutors criminally charged a man with making disturbing calls and texts to his wife, Katie, multiple sources told CBS News.

Former Justice Department officials called the visit unusual, given the historical norm of insulating federal criminal investigations from political officials. The administration and FBI have said Miller's visit was appropriate, pointing to his role at the White House and the administration's broader focus on cracking down on political violence.
