WATCH: Bondi successor reveals shocking number of fraud cases with eye-popping taxpayer theft

"Because of this administration's leadership, fraudsters, scammers, tax cheats or anyone who lies to get rich off the generosity of the American people should be on notice," he said, noting, "Our goal is to prevent this from ever happening again."

Though Bondi's leadership of the DOJ has been heavily criticized, especially by Democrats, Blanche praised her "vision and her commitment to justice." He signaled continuity between her leadership and his, particularly on fraud investigations.

Blanche said, "Every day, Department of Justice investigators and prosecutors work to punish those who commit fraud."

"For example, just this week, and it's only Tuesday, a criminal defendant was sentenced, and the department obtained two additional guilty pleas and matters totaling over half 1 billion dollars in health care and COVID fraud," he said. "If you think about that, just since yesterday, we had a guilty plea in a $160 million health care enrollment fraud scheme, a sentencing in a $100 million COVID-19 fraud case, and a guilty plea in a $160 million health care fraud scheme as well."

He said the DOJ is "supercharging" its efforts through the new division, involving every U.S. attorney across the country in efforts to "take down every fraudster and bring them to justice."

"With over $1 trillion at stake every single year, threatened by increasingly sophisticated and opportunistic fraudsters, the time for this comprehensive and coordinated approach is now," he said, adding, "So, to the fraudsters who seek to take advantage of our nation, let this be a warning."
