Lawyers for Jay-Z are accusing the U.S. Securities and Exchange Commission of engaging in a “celebrity hunt” by trying to compel the hip-hop mogul to testify in the agency’s probe of a firm he did business with more than a decade ago.

Jay-Z, whose given name is Shawn Carter, was willing to testify for a full day, but not “day-to-day until completed” as the SEC is seeking, his attorneys wrote in a court filing dated Monday. The lawyers cited Jay-Z’s concern that the agency’s request “is driven more by governmental fascination with celebrity and headlines than by any proper investigative purpose.” Read more from Bloomberg.
