David Siegal, who has co-chaired Haynes and Boone’s government enforcement and litigation practice for several years, has joined Mintz, Levin, Cohn, Ferris, Glovsky and Popeo as a New York member.

Siegal is best known for obtaining a high-profile defense victory for private equity financier Benjamin Wey in a securities fraud and money laundering case. The Justice Department and the Securities and Exchange Commission voluntarily dismissed their cases against Wey, after a judge suppressed evidence based on deficient warrants.
