SPRINGFIELD, Ill. (AP) -- A Republican candidate for Illinois governor has contributed another $500,000 to his campaign.
Winnetka venture capitalist Bruce Rauner has now pumped $1.25 million of his own money into the four-way GOP primary for the right to take on Democratic Gov. Pat Quinn in 2014.
Rauner filed petition signatures for a ballot position yesterday and also released three years of tax returns. They show he reported more than $53 million in income last year.
He also disclosed ownership stakes in three professional sports franchises, including the Chicago Bulls.
He reported making $28.1 million in 2011 and $27.1 million in 2010.
In a statement, Rauner says he's worked "extremely hard" and feels "incredibly blessed to have earned financial success."
Rauner says if elected he'll put his holdings in a blind trust.
