AUGUSTA, Maine (AP) — The Maine Senate has rejected efforts by state's American Indian tribes and harness horse-racing industry to build casinos.

The Senate turned down six gambling bills late Wednesday.

Among several bills is one that would have allowed Scarborough Downs to build a resort casino which it says it needs to stay afloat and compete with the state's two existing casinos.

Bills that would have allowed the Passamaquoddy Tribe to build a casino in Washington County and the Houlton Band of Maliseet Indians to operate one in Aroostook County also failed.

Opponents say the state must establish a regulatory process to dictate the future expansion of gambling in Maine before it adds any more casinos.

The bills now head to the House where they face further votes.
