Disbarred attorney Evan Greebel—who once represented “Pharma Bro” Martin Shkreli—on Wednesday asked the U.S. Supreme Court to consider his appeal of the U.S. Court of Appeals for the Second Circuit’s ruling that the government may garnish the retirement savings he accumulated during his employment at the law firms Fried, Frank, Harris, Shriver & Jacobson and Katten Muchin Rosenman.

Greebel and Shkreli were each convicted of fraud conspiracy offenses in 2017. Greebel was sentenced to 18 months in prison and ordered to pay $10,447,979 in restitution to victims, and he challenged the government’s effort to enforce the restitution order by garnishing his 401(k) retirement accounts.
