Vice President JD Vance announced Wednesday that the Department of Labor is investigating alleged abuses of the H-1B visa program.

The H-1B program lets U.S. employers hire foreign professionals in specialty occupations that typically require at least a bachelor's degree, including software engineers, scientists, physicians, researchers, accountants, and other highly skilled workers.

"Here's a simple principle, ladies and gentlemen: American jobs ought to go to American workers and not foreign fraudsters, and the Department of Labor is fighting back against it," Vance said while visiting Milwaukee.

Vance said the Labor Department has issued dozens of subpoenas as part of a wide-ranging inquiry.

"Big corporations and fraudsters overseas are using this program to undercut the wages of American workers," Vance said. "If you are trying to take advantage of that visa program, you are not allowed into the United States."

While the Trump administration was saving billions of dollars that had been lost to fraudsters, Democrats looked the other way, Vance argued.

"Not a single congressional Democrat stood up and said we are going to fight back against fraud, and that's the problem with modern congressional Democrats," he asserted.

Vance said his grandparents were blue-collar Democrats who would not recognize what the party has become.

"They would not recognize a party that tries to send your money to illegal aliens instead of our hardworking seniors who earned those benefits and ought to have access to them," Vance said.

"They would not recognize a party that raises your taxes so that we can give more money to the fraudsters, and they would not recognize a party that rewards the fraudsters rather than sending them to prison," Vance added.
