Chicago (CNN) - Illinois gubernatorial candidate Bill Brady will attend Gov. Chris Christie's only public event Tuesday with the Economic Club of Chicago, Brady's campaign manager Dan Egler told CNN.
Brady was Quinn's GOP opponent in the last gubernatorial race, and Christie helped Brady in that campaign.
This comes as the Democratic National Committee and Democratic outside groups are pushing the notion of Christie as a pariah, since there were no public appearances with Republicans in Christie's trips to Florida last month and Texas last week.
The New Jersey governor, whose administration is embroiled in allegations of abuse of power and misuse of Superstorm Sandy relief funds, has a busy travel schedule for his second job as chairman of the Republican Governors Association.
Brady will be in a large crowd of what is expected to be more than a thousand people at the Economic Club event.
When reports emerged over the weekend that Republican candidates in Illinois weren't planning to appear with Christie, the RGA pointed out there were never any plans to make joint appearances because the RGA doesn't get involved in competitive primaries.
The RGA also says the private events in Chicago, as well as the events in Texas last week, are one-on-one meetings and are not designed to included candidates.
The GOP is defending 22 of the 36 gubernatorial seats up for grabs this year, and Illinois is one where Republicans hope to play offense, as Quinn is considered a vulnerable Democrat.
