It is still unclear when the Trump Taj Mahal will close, or if it will. One thing we now know is the casino will be open in Nov. The casino said it still may close by the end of the year. The casino is seeking government funding to help with a rescue plan by Carl Icahn, who owns the note on the casino. The decision to make a statement was in part to ensure visitors that a concert it has planned for the end of the Nov. will take place as planned.
