Virtually overnight after the Supreme Court's repeal of PASPA, FanDuel spawned a multi-billion dollar industry of daily fantasy sports. The intense attention attracted deep scrutiny: state AGs and other regulators aggressively attacked the industry and sought to stop the proliferation of daily fantasy sports in their jurisdictions.

Tusk led an industry-wide mobilization effort to galvanize support among committed fantasy sports players and partners in response to regulatory interference and efforts to curtail the company's growth. Tusk developed and executed an industry-wide plan to protect and legalize daily fantasy sports, while managing media, customer, investor, and partner issues that arose during the next year. Tusk also created FanDuel's Advisory Board, led by former U.S. Attorney Mike Garcia, to validate the integrity of FanDuel's platform and provide ongoing compliance recommendations.

Tusk was able to help FanDuel pass legislation in 16 states and started to plant the seed for many other states moving forward. One of the biggest victories was passing legislation in New York State. The NY legislation was a big win for FanDuel as one of the country's largest markets for sports fans and paved the way for similar legislation in other states that had previously sought to ban daily fantasy sports. FanDuel was fully acquired by Flutter in 2020 for $11B.
