Billionaire businessman J.B. Pritzker has launched a bid for Illinois governor at a park facility in Chicago.
The Democrat's entry into the race raises financial stakes in what was already expected to be a costly and competitive fight to unseat Republican Gov. Bruce Rauner.
Pritzker wasted little time in blasting the venture capitalist-turned-governor, even comparing him to President Donald Trump. Rauner has been at odds with the Democrat-controlled Legislature since he took office.
