Arguing that convicted lawyer Evan Greebel should be sentenced to no less than five years in prison, federal prosecutors pushed back against the scores of letters seeking leniency for Greebel, including some former law firm colleagues who said Greebel, a former adviser to Martin Shkreli, had an encounter with “the devil.”

“If Shkreli was the devil, Greebel happily made several deals with the devil,” prosecutors said, writing that Greebel “wholeheartedly embraced his relationship” with Shkreli, a former pharmaceutical executive, to serve his own needs. When Greebel left Katten Rosenman Muchin in 2015 to join Kaye Scholer as a partner, he was given an $800,000 base salary, nearly double his Katten compensation, they said.
