Markwayne Mullin, the Secretary of Homeland Security, made the claim in remarks reported by the New York Post on 31 October 2026.

Our verdict

Unverified

We could not confirm or refute this claim. Independent reporting backs the idea that the investigation involves multiple people, but the specific assertions that the case was presented to the Department of Justice and that the DOJ is leading it rest only on Markwayne Mullin's own statements, with no independent confirmation of a formal referral or lead-agency role.

What we found

The claim has several parts. The part about the investigation involving multiple people is supported by independent reporting, including an NBC News report on 14 October 2026 and an MPR News report on 28 October 2026, which describe subpoenas to family members and other individuals. The statements themselves are also well documented: the New York Post, CBS Austin and ABC News 4 all reported on 31 October 2026 that Mullin said the case was large, involved multiple people, had been presented to the DOJ, and that the DOJ was leading the investigation. However, the two central parts of the claim — that the case was formally presented to the DOJ and that the DOJ is leading the investigation — could not be confirmed by any source independent of Mullin. Other reporting, including an MPR News piece and a letter from Representative Pramila Jayapal's office, confirms that the DOJ is involved: it secured a search warrant, handled court documents and took part in a search. But that is not the same as showing a formal referral from the Department of Homeland Security to the DOJ, or that the DOJ is the lead agency rather than a partner such as Homeland Security Investigations. Because those elements cannot be verified from public evidence, our verdict is unverifiable.
