The House Energy and Commerce Committee's subcommittee on Commerce, Manufacturing and Trade plans a hearing in Washington on Wednesday on the issues of daily fantasy sports.
Geoff Freeman, president of the American Gaming Association, said fantasy sports operate in an illegal "gray zone" and the casino industry wants to see clear rules on where sports betting is going to be legal, how it's going to be regulated and how consumers are going to be protected.
Freeman said sports betting is a thriving $150 billion industry, with $4 billion of that wagered legally in Nevada.
Sports betting is illegal in most states under the Professional and Amateur Sports Protection Act of 1992 and he said, "Times have changed since prohibition became federal policy."
Even the major sports leagues support fantasy betting, he said, and the integrity of professional sports already is at risk because of illegal sports betting.
