James Comey tells court Secret Service surveillance in “8647” threat case was “illegal,” filings say

James Comey, the former FBI director, has asked a federal court to consider an accusation that Secret Service personnel “illegally” surveilled him in connection with a case related to a purported threat linked to his Instagram activity, according to a court filing reported by CNBC on July 29, 2026. The dispute centers on Comey’s decision to post a photo of seashells that he says formed the numbers “8647.”

In the court filing described by CNBC, Comey argued that authorities treated his Instagram post as threatening and moved to monitor him. He characterized that conduct as part of what he called vindictive or retaliatory prosecution, asserting that the government’s approach went beyond lawful investigation boundaries. CNBC’s report frames Comey’s position as a challenge to the legality of the surveillance itself, not just the underlying allegation about the meaning of the “8647” imagery.

The “8647” matter is presented in the reporting as part of a broader case involving alleged threats during the Trump administration. CNBC’s story ties the surveillance allegation to the Secret Service, the federal agency that is responsible for protecting the president and other designated individuals and that can also become involved in investigations when officials believe credible threats may be involved.

Comey’s filing also places the episode in a speech and due-process context, according to CNBC’s account. By arguing that the surveillance was unlawful, Comey is contesting the government’s authority and procedures used after he posted the seashell image on social media. The practical question raised for the court, as described by CNBC, is what role surveillance evidence or monitoring played in the case and whether it was gathered in a manner consistent with constitutional and statutory limits.

Because the court filing is at the center of the dispute, the legal next steps described by the reporting depend on how the judge handles Comey’s challenge. In general terms, such claims can affect whether particular evidence is admitted or how factual questions are evaluated, but what is ultimately decided will turn on the arguments set forth in the filing and the court’s rulings.

The reporting indicates the dispute is connected to how authorities interpreted the “8647” numbers in the threat-related case. Comey’s position, as described by CNBC, is that the post should not have been treated as a threat and that the government’s monitoring activity therefore reflects an improper exercise of investigative power.

The case also highlights how fast-moving threat assessments can intersect with protected communication. In this instance, Comey’s challenge asserts that the government’s reaction to a social-media post escalated to surveillance that he says crossed legal boundaries, underscoring that courts may need to weigh the government’s stated threat concerns against constitutional safeguards in deciding what evidence may be used.

As the matter proceeds, Comey’s legal team will seek to have the surveillance issue addressed through the court’s procedures, while prosecutors will respond with their legal justification for the surveillance and their interpretation of the underlying threat allegations tied to the “8647” post, according to the dispute described in CNBC’s report.
