ATLANTIC CITY - Billionaire Carl Icahn would not be able to retain the casino license for his now-shuttered Trump Taj Mahal under a measure making its way through the New Jersey Legislature.

Seeking to avoid the possibility of Icahn keeping the casino shut during the winter and attempting to open it in the spring as a non-union facility, Democratic Senate President Steve Sweeney has introduced a bill that would disqualify casino owners from holding a gambling license for five years after closing a casino.

Union leaders and many former Taj Mahal workers suspect Icahn will try to reopen the casino next year without the union.

An Icahn spokesman wouldn't comment on plans for the Taj Mahal but noted that none of the other four Atlantic City casinos that have closed since 2014 have reopened.
