Homeland Security Secretary Kristi Noem issued an ominous warning to California Gov. Gavin Newsom (D) after President Donald Trump announced a fraud investigation into the state of California.

“Oh, we’ll be there,” she boasted to Fox News’ Jesse Watters on Tuesday. “We think that this is just the tip of the iceberg. So Minnesota is unbelievable, what we’ve seen, but it is leading us to networks all over the country and overseas, and we’re gonna follow every single one of them.”

In recent weeks, Trump has been using allegations of fraud at day care centers as grounds for increased federal law enforcement actions in Minnesota. Some of those actions have had deadly consequences.

Calling Homeland Security Investigations “an incredible team of individuals who go after human traffickers [and] sex traffickers,” Noem said that “the fraud that we have in our public programs” is “absolutely” tied to California.

“We’re gonna come to you, Governor Newsom, and we’re going to arrest every single individual that has ties to this kind of stealing of taxpayer dollars and we will hold them accountable,” she added. “We’ll bring them to justice.”

Trump announced in a Truth Social post on Tuesday that a “Fraud Investigation of California has begun,” but did not provide any specific details about the alleged probe.

“California, under Governor Gavin Newscum, is more corrupt than Minnesota, if that’s possible??? The Fraud Investigation of California has begun. Thank you for your attention to this matter!,” the president wrote.

Newsom’s press office responded to Trump’s claims in an X post on Tuesday, writing “HAHAHAHAHA. Donald Trump is a deranged, habitual liar whose relationship with reality ended years ago.”
