De La Hoya has recorded a robocall promoting passage of Question 7, which would allow a casino in Prince George’s County, as well as table games, such as black jack and roulette, at Maryland’s five previously authorized slots sites.

In the call, De La Hoya relays that as a boxer, he “slugged it out” at two venues in Las Vegas owned by MGM Resorts — the company angling to build a casino at National Harbor.

If MGM comes to Prince George’s, the county will get a similar “destination resort” that will create “thousands of jobs for hard-working people,” De La Hoya says.

The ad is sponsored by Maryland Jobs & Schools, a pro-gambling ballot issue committee to which MGM has given more than $18 million for an ongoing advertising campaign.

A previous robocall by the same committee featured David Copperfield, the world-famous magician.

A long list of other athletes, actors and musicians have previously gotten involved with both the expanded gambling campaign and one to legalize same-sex marriage in Maryland.
