Republican candidate for Illinois governor Bruce Rauner says he'll release his 2013 income tax returns once they're ready.
Rauner Spokesman Mike Schrimpf says Rauner got a six-month extension of the April 15 filing deadline. He says Rauner will make his returns public before the Nov. 4 election.
Democratic Gov. Pat Quinn's campaign has called on Rauner to release his 2013 returns and more information about prior years as the two face off in a highly competitive race.
Schrimpf says it's "nothing but a political stunt." He says Rauner pro-actively released three years of returns.
Quinn's 2013 returns show he made about $161,000 last year. Rauner's 2012 returns show the Winnetka businessman made $53 million that year.
Quinn was set to hold a news conference on the issue Tuesday afternoon.
