"Putting an extra layer in is not going to help," Gilliam said. "And one layer is not gonna stop any, it may stop one part of the fraud, it's not really gonna make any difference overall."
Gilliam said Democratic Minnesota Gov. Tim Walz committed "at the minimum malpractice" by the sheer amount of fraud that was committed in his state.
The move comes after federal prosecutors announced in mid-December that 14 programs in the state contained fraud, adding those programs cost Minnesota taxpayers $18 billion since 2018.
"When I say significant, I'm talking in the order of half or more. But we'll see," Thompson said. "I think a significant portion."
Thompson revealed during the news conference that six more people were recently charged in connection to an alleged Minnesota housing services fraud.
In one case alone, the defendant is accused of submitting $1.4 million in fraudulent claims, then using some of the money to buy cryptocurrency. That person fled the country after being subpoenaed, Thompson added.
In one of the larger fraud cases gripping the Land of 10,000 Lakes, the Feeding Our Future scheme cost taxpayers nearly $250 million, after the program's director approved nonexistent meal services going to poor people.
Criminal defense attorney Sam Bassett told Fox News Digital that someone likely should have detected the fraudulent activity well before it escalated to this point.
"I think it remains to be seen when the details come out, but it does have that tenor about it right now that somebody should have done something sooner. Maybe this should have been detected much sooner to prevent continued violations," Bassett said.
Fox News Digital reached out to Walz's office and DHS for comment.
