Jeffrey Epstein's relationship with Paul Weiss chairman Brad Karp and his client Apollo Global Management led to the law firm's entanglement in Epstein's affairs. Karp, who led Paul Weiss during its explosive growth from $665m to $3.25bn revenue largely fueled by Apollo, advised Epstein on matters including a $158 million fee dispute with Apollo founder Leon Black. Karp also assisted Black in dealing with Epstein's associate Guzel Ganieva, who alleged extortion by Black.

Paul Weiss hired private investigators to surveil Ganieva at Black's request, and Karp exchanged cryptic messages with Epstein. Apollo denies any wrongdoing, citing its own investigation. Karp's role in these matters contributed to his eventual resignation from Paul Weiss.

This scandal highlights the complex, ethically fraught relationships between elite law firms, private equity giants, and Epstein, raising questions about conflicts of interest and the firm's transformation under Apollo's influence.
