A report in Chicago shows Republican Bruce Rauner's (ROW'-nurz) former private equity firm set up investment funds in the Cayman Islands - including ones in which he has a personal financial interest.

The disclosure stirred up a new round of calls from Democratic Gov. Pat Quinn's campaign for his Republican rival to fully disclose his financial holdings.

Rauner was in charge of the Chicago-based firm GTCR when it set up a dozen funds from 2009 to 2011 in the Caribbean nation known as a tax haven. The Sun-Times reports that three of those are funds in which Rauner has a personal interest, which reported earlier this month.

Rauner spokesman Mike Schrimpf says the investments are legal "flow-through" funds and a "common" device in investment strategy.
