DOGE discovered a sudden surge in SSN allocations they didn't expect to uncover. 2M SSNs were given to illegals for "tax purposes" when they worked.
While a lot of 110+ year olds have been found to be getting SS payments, it's possible that many may just be date errors that need to be checked before just stopping payments. All this data needs to be analyzed to stop the fraud and waste:
Issued FY starts in previous year Sept->October of current year: FY21: 270,425 FY22: 590,193 FY23: 964,163 FY24: 2,095,247 FY25: 900,649


The source on this stat is Musk's presentation at a political rally. There's not even an official government source on these stats. (If there is link it.)
Musk has repeatedly lied in the past about matters of fact and import. I think only a fool would believe these stats without evidence.
