Frank Bisignano, the IRS chief and Social Security Administration head, is entangled in a decade-long legal dispute with sports memorabilia collector Eric Inselberg over Muhammad Ali's 1977 boxing shorts. The shorts, worn during Ali's fight against Earnie Shavers, are central to the conflict. Bisignano's dual roles have complicated the case, with the IRS seeking to reclaim what it considers federal property.

Inselberg, who claims ownership through a private purchase, counters that the shorts are his. The legal battle underscores tensions between federal asset management and private collectors of sports history.
