The Trump administration is ramping up a nationwide crackdown on the misuse of taxpayer money. A top federal prosecutor criticized California Gov. Gavin Newsom over a lack of oversight, branding him the "king of fraud."

"California has spent $24 billion in the last five years on homelessness, and no one can account for where that money has really gone," First Assistant U.S. Attorney for the Central District of California Bill Essayli said Thursday on "Fox & Friends."

In April, Essayli launched a task force to investigate corruption in California, with a focus on homeless services. The task force has already resulted in federal charges against two men accused of using real estate projects to exploit the state’s homelessness system for personal profit.

Essayli said those cases, which involve millions of dollars in alleged fraud, are only the "tip of the iceberg."

"We already charged millions of dollars in fraud," he said.

"I can tell you more charges are coming, probably as soon as this month."

He accused Newsom and California’s Democratic leadership of allowing fraud to continue in state-run programs with little oversight or accountability.

The scrutiny of California comes as other Democrat-led states face similar federal probes of benefits programs. In Minnesota, federal authorities are investigating allegations of widespread fraud involving childcare and other social services.

President Donald Trump weighed in on Truth Social, suggesting California could be "more corrupt" than Minnesota.

"The Fraud investigation of California has begun," he wrote on Tuesday.

Newsom’s press office pushed back against the accusations, writing on X that the governor has "blocked over $125 BILLION in fraud, arrested criminal parasites leaching off of taxpayers, and protected taxpayers from the exact kind of scam artist Trump celebrates, excuses, and pardons."

Vice President JD Vance has also criticized California’s welfare policies, accusing the state of providing benefits regardless of immigration status. Speaking to Fox News’ Jesse Watters, Vance said California openly advertises using taxpayer funds to provide Medicaid to illegal immigrants.

"California, more than almost any other state, has been so glaring and obvious about the fact that they're giving welfare benefits to illegal aliens," said Vance.

"They're getting rich off of the generosity of the American taxpayer. The political corruption that enables it has got to stop," he added.

Vice President JD Vance fired back at Rep. Jasmine Crockett, D-Texas, for criticizing the Trump administration's successful operation that captured Venezuelan dictator Nicolás Maduro and his wife, Cilia Flores, over the weekend.

"Jasmine Crockett, of all people, has the least amount of room to talk on this stuff. She doesn't know what she's talking about," Vance told "Jesse Watters Primetime" on Wednesday. 

"As the president said, you couldn't have a worse spokesperson, a person with less knowledge about world affairs. It's telling that she's the person speaking for the Democrats on this issue."

During an appearance on "The View" on Monday, Crockett sharply criticized President Donald Trump, likening him to Maduro and accusing him of undermining democratic norms.

"As we sit here on Jan. 6, I do want to be clear, somebody else was trying to be a Maduro of the United States. Somebody else wanted to do the exact same thing. The difference is Maduro was successful. I also want to point out that we now in the state of Texas and around this country are enduring this ridiculous redistricting scheme. Again, because he [Trump] doesn’t really believe in free and fair elections," she said during the show.

Crockett also argued that Trump’s strikes in Venezuela were out of self-interest rather than for the benefit of the Venezuelan people. She framed the operation – namely the overnight capture of Maduro – as effectively a kidnapping, warning that Americans would be outraged if another country acted the same way toward U.S. leaders.

"This ain’t about Venezuelans. I get that there are people that don’t like the leader. But guess what, there are a lot of people that don’t like our leader," she said.

"And regardless, somebody coming into the United States and grabbing our leader in the middle of the night and killing people in this country, I’m sure everybody would be outraged at them doing it that way."

Vance pushed back on that characterization, defending the operation as lawful and justified.

"We engaged in a law enforcement action. We had a legitimate indictment from Maduro for narco-terrorism, for weapons smuggling and weapons trafficking, and we went in with the best military in the world, we got our guy, he's going to stand trial," Vance said.

"By the way, he is given the full due process rights that are entitled to anybody who's in the United States. I think he's going to go away. He's going to be found guilty. That's not a kidnapping, that's a law-enforcement operation."
