President Joe Biden granted clemency to nearly 1,500 Americans this week, including to a former doctor convicted of Medicare fraud for providing diluted chemotherapy drugs to cancer patients.

The commutations, which the White House is lauded as “the largest single-day grant of clemency in modern history,” has drawn significant criticism as some of those on the list have been reported on. According to a report from The Washington Free Beacon, several recipients were involved in serious offenses.

Meera Sachdeva, a Mississippi doctor, was sentenced to 20 years in prison in 2012 for defrauding Medicare and was required to reimburse $8.2 million to her former cancer facility. Sachdeva provided cancer patients with diluted chemotherapy drugs. She also provided them with old needles, which resulted in one patient claiming to have gotten HIV from a needle used by her clinic.
