During a tele-town hall with Wisconsin voters Monday night, Elon Musk revealed that an arrest is expected in connection to a major Social Security fraud operation involving the stolen identities of over 400,000 Americans.

The fraud, Musk alleged, is part of a broader effort that includes the exploitation of U.S. welfare systems and voter rolls by illegal immigrants.

Musk made the remarks while addressing voters in Wisconsin, responding to a question from a caller in Pulaski who asked whether the fraud uncovered in the Social Security system would be prosecuted.

“Yes. In fact, I believe someone is going to be arrested tomorrow,” Musk said.

“This is someone who actually stole 400,000 Social Security numbers and personal information from the Social Security database, and was selling Social Security numbers and all the identification information in order for people to basically steal money from Social Security.”

Musk said the method of fraud has far-reaching implications, including misuse of government benefits and unauthorized participation in the U.S. election system.

“This is a particular avenue of fraud for illegal immigrants and for voter fraud, because the main way that identification is established in the United States is via Social Security,” Musk explained.

“So if you compromise the Social Security system, you can basically get people de facto registered to vote, even if they’re not citizens, and to get a bunch of benefits and milk the system. It’s pretty insane.”
