New Jersey regulators have given final approval for Atlantic City's Showboat Casino Hotel to shut down on Aug. 31.
The Gaming Enforcement Division's action comes as a state senator pushes a constitutional amendment to put slot machines at the state's four horse racing tracks.
Division Director David Rebuck signed an order Monday night authorizing the Showboat to shut down at 4 p.m. on Aug. 31.
It's one of three Atlantic City boardwalk casinos closing in the next few weeks.
Revel will close its hotel Sept. 1 and its casino Sept. 2, and Trump Plaza is closing Sept. 16.
Senator Joe Pennacchio's proposal would have voters decide whether to amend the state constitution to put slots at the tracks, run by a group of Atlantic City casinos.
