Republican presidential candidate, former Massachusetts Gov. Mitt Romney speaks during a campaign rally at Alice Pleasant Park on May 29, 2012 in Craig, Colorado.
Republican presidential candidate Mitt Romney raised $3.3 million on Thursday during a visit to President Barack Obama's stronghold of Chicago.
The GOP candidate attacked his rival on the economy, his energy policies and other programs he says has held back the economic recovery at a hotel in the affluent Gold Coast neighborhood, just a few miles north of Obama's campaign headquarters.
As his party's presumptive nominee, Romney is engaged in an increasingly frantic race for campaign cash.
In his speech to supporters, Romney said the president has failed to hold down unemployment and kept business owners from creating new jobs.
Earlier in the day, Romney and Obama laid out differing visions of how to spur America's sluggish economy in dueling speeches in Ohio.
The president will follow Romney to Chicago on Friday when he and Michelle Obama hit town to attend the backyard wedding of Senior Adviser Valerie Jarrett's daughter.
