Donald Trump says Atlantic City's 11 casinos should sue to block a smoking ban from taking effect in October.

The real estate magnate, who is chairman of a company that owns three casinos in Atlantic City, says the Atlantic City Council put New Jersey at a competitive disadvantage when it approved a ban Wednesday night.

Trump called on the Casino Association of New Jersey to file a lawsuit seeking to overturn the ban. However, Trump said he would not file one on his own.

The association's president did not immediately return a call for comment. Joseph Corbo has previously said the industry would reluctantly go along with a ban if it had enough time to prepare.

The ordinance allows casinos to construct gambling-free smoking lounges.
