ATLANTIC CITY, N.J. (AP) — The gambling industry’s national trade association is asking the federal government to crack down on illegal betting sites, saying consumers need to be protected.

The American Gaming Association is asking the Justice Department to investigate and prosecute the largest illegal bookmaking operations.

Association president Bill Miller says the illegal sites are brazenly defying U.S. and state laws, without offering any legal protection to customers. The Justice Department did not immediately respond to a request for comment.

Sports betting is legal in 33 U.S. states, including South Dakota, and Washington D.C.
