Daniel Mark Porush (born February 1957) is an American businessman, former stock broker and convicted criminal who helped run a pump and dump stock fraud scheme in the 1990s at the Stratton Oakmont brokerage in collaboration with Jordan Belfort. In 1999, he was convicted of securities fraud and money laundering, for which he served 39 months in prison. After prison, Porush became involved with a Florida-based medical supply company, Med-Care, which was the subject of federal investigations. In the biographical 2013 film The Wolf of Wall Street, which focuses on the story of Belfort and Stratton Oakmont, Jonah Hill portrays Donnie Azoff, a character loosely based on Porush. Porush has called the portrayal inaccurate and threatened to sue the filmmakers to prevent him from being depicted.
