Stephen Miller, the White House homeland security adviser, went to FBI headquarters on Tuesday of last week and spoke at a training conference for counterterrorism agents, CBS News reported, citing multiple sources. Two days later, the U.S. Attorney’s Office in Boston charged a Massachusetts man, John A. Proia, with one count of cyberstalking Miller’s wife, Katie, and their family. Proia has pleaded not guilty.
Here is why the timing matters. American criminal justice has a rough division of labour, and it has held since Watergate. The White House sets priorities. The Justice Department and the FBI decide which particular people to investigate and charge, and political officials are supposed to stay out of individual cases. Crime victims get some say, but they generally don’t get to brief the agents. Imagine you are a counterterrorism supervisor sitting at that conference. The president’s homeland security adviser is at the front of the room telling you to be more aggressive about threat cases, and you know one of the open threat cases involves his family. You don’t need anyone to give you an order. You can work out the incentive yourself.
What did Miller actually say? According to a source briefed on the meeting and a senior FBI official, he told the agents that President Trump’s push against domestic terrorism was personal to him, and he cited the 2025 assassination of his friend Charlie Kirk, the founder of Turning Point USA. The FBI official said Miller argued that federal agents should be more proactive, and that no case is too small, whether the threats are aimed at a congressman, a spouse, friends, loved ones or a speaker on a college campus. The official described this as part of a wider effort to get ahead of mass-casualty attacks by pursuing threats and harassment, because those crimes can come before violence. The audience was FBI assistant special agents in charge who specialise in counterterrorism, plus officials from IRS Criminal Investigation, Homeland Security Investigations and the Secret Service.
The administration says none of this is a problem. “As Homeland Security Advisor, Stephen Miller interacts with all law-enforcement agencies on a regular basis related to public safety, national security, and counterterrorism,” a White House spokesperson said. An FBI spokesperson said Miller “has been a valued partner in this work – and the conference was thrilled to have him be a part of discussing the important priority.”
Several former Justice Department officials told CBS that a White House adviser taking part in an FBI training conference is not customary, and that this case is odder still because Miller is an alleged victim and potential witness in the Boston case. “Politically well-connected people who are related to victims do not have a right to jawbone FBI supervisors to do what they want them to do, and if they are political and throwing around their political connections, it’s even worse,” said Jeffrey Breinholt, a longtime former counterterrorism prosecutor at the department.
The reassignments
In the days before the speech, Darren Cox, who leads the FBI’s Washington Field Office, moved its two most senior counterterrorism agents into other roles. Sources told CBS this came after the Millers complained that the investigation into the Massachusetts man was moving too slowly. Bloomberg Law first reported the removals, which rews covered last month. CNN reported that the Washington counterterrorism team had first concluded the matter needed no further investigation, and that investigators in Boston also had reservations.
The official accounts agree that the Millers did not ask for anything. The White House says they never spoke directly to the reassigned agents and never requested a personnel change. Beyond that, the accounts drift apart a little. A White House spokesperson said senior FBI leadership had found the agents were “stifling investigations into very serious threats and made a unilateral decision to remove them.” Cox said: “This was a personnel decision made at the Washington field office level alone based on our constant evaluation of mission needs. Any suggestion otherwise is false.” Chris Raia, the FBI’s deputy director, said the decision rested on “a number of factors” that media reports have not reflected. The bureau said it pursued the Miller-related cases “based on appropriate predicate and evidence of alleged crimes — not because the White House ordered an investigation.”
The case itself is a federal grand jury indictment. As The Hill and others reported, prosecutors say Proia, 41, of Waltham, sent threatening messages and vulgar voicemails to Katie Miller, her husband and her parents between Aug. 3 and Sept. 23, and contacted her at least 40 times, using free internet calling apps. The FBI’s Joint Terrorism Task Force made the arrest. “As alleged in the Indictment, the defendant repeatedly and relentlessly targeted the victim, her husband and her family with deeply disturbing communications that profoundly disrupted their lives,” said U.S. Attorney Leah Foley. The charge is ordinary cyberstalking, not a terrorism offence.
The Arlington case
This is at least the second time the Millers have pressed the FBI for a case. Last fall, they asked Virginia officials and the FBI to investigate Barbara Wien, an Arlington activist who protested outside their home and handed out flyers with their address on them. The Millers then moved into military housing. A magistrate judge twice rejected a federal search warrant, according to CBS. Sources said Miller kept pushing anyway. He asked for counterterrorism agents to go undercover in his neighbourhood’s political activist group, and he regularly called the U.S. Attorney’s Office in the Eastern District of Virginia for updates. As recently as December, agents were interviewing Wien’s neighbours and acquaintances, even though they still had no warrant for her phone. One source said the investigation was still open this summer.
The state side went no further. Parisa Dehghani-Tafti, the commonwealth’s attorney for Arlington and Falls Church, formally declined to prosecute earlier this year, writing in a court filing that “nothing in the proceeds of the search warrant supports criminal prosecution.” Her office is the same one prosecuting Colin DeMarco on state charges of attempting to murder Russell Vought, the budget director. Sources told CBS her office took that case after federal prosecutors in the Eastern District declined to bring charges.
The policy
The training was built around National Security Presidential Memorandum-7, which the White House issued on Sept. 25, 2025. It puts the FBI-led Joint Terrorism Task Forces in charge of a national strategy against domestic terrorism and political violence, and it tells the attorney general to prioritise those cases. Miller is responsible for carrying it out. There is no federal domestic terrorism statute, so prosecutors use other laws and seek terrorism enhancements at sentencing. Some charges, such as material support or civil disorder, need consultation or approval from the National Security Division. Then-Attorney General Pam Bondi’s December memo widened the kinds of crimes that could be treated as domestic terrorism, adding things like doxxing law enforcement officers. It also told agents to focus on people with “extreme viewpoints on immigration, radical gender ideology, and anti-American sentiment” who are willing to use violence.
The FBI’s position is that the Boston case went forward because of the evidence, not because of a phone call from the White House. That is the correct answer, and it may well be true. It is just harder to say convincingly in a week when the White House was physically in the building, telling the people who decide which cases to pursue that no case is too small.
