Evan Greebel, a Kaye Scholer partner who faces federal wire fraud charges, also is coping with two internal investigations into his work for the controversial pharmaceutical executive Martin Shkreli, who federal prosecutors say ran a Ponzi scheme.

Greebel, 42, remains at Kaye Scholer, though the firm announced last week it had launched an internal investigation into his alleged misconduct. A spokeswoman for Katten Muchin Rosenman, where Greebel practiced before joining Kaye Scholer in July, confirmed Monday that Katten is conducting an internal inquiry as well into Greebel’s work for Shkreli.
