How much money is the U.S. government losing to fraud in federal programs?

According to James Freeman, there is a massive problem with fraud in federal programs in the United States. The government is facing a gap of almost $2 trillion between what it spends and what it collects in revenue, with a significant portion attributed to fraud in federal programs. Freeman suggests that addressing this fraud issue could help reduce the spending gap without cutting useful programs. This fiscal mismanagement represents a substantial waste of taxpayer dollars that could be redirected to more beneficial purposes or help close the federal budget deficit.
