This estimate doesn't come from us or DOGE, but the U.S. government's OWN auditors.
Bravo to - of all places - 60 Minutes for their interview with Linda Miller, formerly a chief investigator at the Government Accountability Office, who has tracked how taxpayer money is misspent. GAO's official assessment is that taxpayers are victims of $520 billion a year in fraudulent and "erroneous" payments.
But here is Miller's assessment as featured on 60 Minutes:
"I believe the government is losing between $550 billion and about $750 billion a year. We're coming up close to the $1 trillion amount-- is lost, every year, to fraud."
