Chicago Mayor Rahm Emanuel has joined the call for Republican gubernatorial candidate Bruce Rauner to make his complete 2013 income tax records public.

“Running for office and releasing your taxes is like a rite of passage. You have to do it,” said Emanuel, who released his 2013 tax returns and the accompanying schedules on Friday.

“When I ran for Congress, I released my taxes," added the mayor, reported the Chicago Sun-Times. "When I ran for mayor, I released my taxes. I released my taxes when I was [White House] chief of staff, even though I was not in elected office, but it was an office in the public trust. I do believe in a separation. You’re still allowed a personal life and a private life. Your taxes, though ... they speak to what I think is the right thing to do. And it’s a rite of passage running today for office, especially chief executive.”

Rauner plans to make his most recent tax returns public no later than October 15. However, he has not promised to release the schedules that go with his taxes.

The GOP gubernatorial hopeful responded to Emanuel's call while speaking with reporters in Springfield. 

"Everybody’s got their opinion," Rauner said. "We have released far more than is required under the law. We’ve released multiple years of our tax returns."
