Trump administration officials have been making efforts throughout the year to keep people from relying on food stamps and other forms of welfare, but they have also made strides in taking down criminals committing food stamp fraud for financial gain.

The food stamp program is a federally-funded program administered by the U.S. Department of Agriculture (USDA), and federal investigators with the agency are most often the ones who catch those engaged in fraudulent activities.

Sometimes, these investigations can occur at the state level because state agencies are responsible for administering welfare programs such as food stamps.

Investigators often uncover millions of dollars worth of food stamp fraud, mostly from people who run convenience stores in low-income areas where many customers receive food stamps through the Supplemental Nutrition Assistance Program (SNAP).

To show how many millions of dollars these criminals have stolen from the federal government in 2018, here are the ten biggest takedowns of food stamp fraud this year.
