INDIANAPOLIS (AP) — The question of whether Indiana will allow sports betting by mobile devices is still up for debate in the state Legislature.

The Indiana House voted 78-15 Monday in favor of a bill that includes limiting the legalization of sports wagering to casino sites. The state Senate previously supported permitting online sports betting , so lawmakers face a deadline later this month for reaching agreement on what to allow.

Some House members who oppose allowing sports bets by mobile devices call it a significant expansion of gambling that could lead to traditional casino games moving online.

Republican Rep. Allan Morrison of Brazil argued Monday that limiting sports betting to casinos will mean a big loss in tax revenue.

The bill would also allow new casinos in Gary and Terre Haute.
