Sensenbrenner, the Chairman for the House Subcommittee on Crime, Terrorism, Homeland Security and Investigations, has suggested Congress must act in some way following the Supreme Court's repeal of the Professional and Amateur Sports Protection Act in May.

In September, representatives at a House Judiciary Subcommittee sports betting hearing discussed sports betting legislation, with the Nevada Gaming Control Board and American Gaming Association testifying against the need for federal involvement.

However, writing in a public letter, Sensenbrenner has re-addressed the issue, although he stopped short of recommending federal oversight.

He wrote: "After hearing from a panel of experts representing a broad range of positions related to sports betting, it is clear Congress has work to do to ensure the public is protected, and any potential for exploitation by criminals is minimised in this post-PASPA era.

"To protect the American public and limit the ability of nefarious organisations from exploiting internet gambling, I believe Congress will develop a legislative response to the issues created by the Supreme Court’s decision striking down PASPA."
