Illinois lottery winners who weren’t paid because of the state’s budget impasse have filed a lawsuit contending they are owed interest accrued during the months winning tickets weren’t honored.  Thomas Zimmerman, attorney for the plaintiffs in the class-action lawsuit filed Thursday in Cook County Circuit Court, told the Chicago Tribune he estimates interest accrued on withheld lottery winnings to be about $1.5 million.  Lottery officials didn’t return a request Friday for comment.  Illinois stopped paying out winnings of more than $25,000 on July 1, 2015.  A lawsuit was filed by lottery winners in September.  In October, Illinois halted all payments on winnings of more than $600.  Payments resumed in December after Governor Bruce Rauner and House Democrats agreed to release $3.1 billion for municipal 911 centers and lottery winners.
