Authorities say his name was the final sign-off on contracts over $100,000 before Noem's signature, prompting complaints that he could profit from the process. Noem denied during a Senate hearing that he approved contracts. Lewandowski's attorney adamantly denies any demand for payment or compensation.
Both Lewandowski and Noem have denied an affair; Noem called questions about sexual relations 'tabloid garbage' in committee. The controversy follows a history of high-profile exits for Lewandowski, and comes after Noem was fired earlier this month.
