Between September 2020 and July 2023, Crowder was a veterans service representative employed by VA when he assisted thirteen veterans with preparing their claims for retroactive disability benefits.

Dr. Claribel Tan, and her husband, Daniel Tan, pleaded guilty to executing a $12.5 million healthcare fraud scheme and evading more than $4 million in taxes on the profits of a decades-long scheme. The Tans operated a rheumatology medical clinic in Anchorage and specialized in the treatment of autoimmune and musculoskeletal diseases. Beginning in 2009, Dr. Tan routinely and surreptitiously underdosed patients, injected them with free samples or a different medication than prescribed, injected them with expired medication, and/or injected them with medications purchased by other patients. The Tans then knowingly billed insurance plans as if Dr. Tan had provided each patient a full and proper injection. This case was investigated by the VA OIG, Defense Criminal Investigative Service, IRS, FBI, Defense Contract Audit Agency, Department of Labor Employee Benefits Security Administration, Food and Drug Administration, and State of Alaska Division of Insurance Investigation Unit.

Daniel Rikkels of Chula Vista, California, was indicted by a federal grand jury on charges that he helped veterans fraudulently obtain disability benefits while he was a VA employee responsible for reviewing and approving disability claims. Between 2020 and June of 2025, Rikkels knowingly and intentionally instructed veterans to provide false, exaggerated, and misleading claims of service-related injuries to support their disability claims. Rikkels also instructed veterans to alter documents submitted during the claims process. Through these false claims, veterans fraudulently obtained millions of dollars in VA disability payments and backpay, and Rikkels received millions of dollars in payments from the veterans in return for his work on their behalf. The VA OIG and the FBI investigated this case.

Roy Lee Holt, of Harper Woods, Michigan, allegedly obtained more than $60,000 in COVID-19 relief funds and Paycheck Protection Program (PPP) loans fraudulently.

He is further accused of submitting additional fraudulent misrepresentations to have those loans forgiven. Each PPP loan Holt received was for $20,832.

The CERA program supported Michigan residents struggling with rent and utilities due to pandemic-related financial hardships. At the time this fraud is alleged to have been committed, Holt was a VA employee. He was charged with three felony counts of false pretense in varying amounts, two felony counts of using a computer to commit a crime, and one felony count of making or permitting a false tax return. The VA OIG and Michigan State Housing Development Authority investigated this case.
