Even if General Assembly approves, Maryland voters would have a say on table games and a new casino location in a statewide referendum.

Prince George's County Executive Rushern Baker is scheduled to testify in support of building a high-end casino at National Harbor near the nation's capital.

Senate President Mike Miller favors the National Harbor site noting it would attract gamblers from nearby Washington DC and Virginia.

Currently, Maryland only allows five slot machine casinos. Two have opened so far, with a third expected to open this summer near Arundel Mills Mall in Anne Arundel County.

David Cordish, whose company is building the Arundel Mills casino, opposes expanding gambling. He told WBAL News the state should allow the five casinos allowed under the law to open, before allowing any additional casinos.Cordish's site would be the closest to any National Harbor casino.

The state's slots commission is currently reviewing applications for slots casinos in Baltimore City and at Rocky Gap State Park in Western Maryland.
