The Trump Taj Mahal is working on a last ditch effort to keep the casino open. As a result, the casino is now promised to stay open until Dec. 20. Workers have been notified the casino is staying open a week longer than initially thought. Billionaire Carl Icahn is viewed as the casino’s last hope to stay open, but he is requiring a number of givebacks, including state aid. If the Trump Taj Mahal closed it would be the fifth casino this year.
