Republican Senate candidate Kevin Nicholson's consulting clients includes companies owned, or invested in, by Pritzker Group, a financial firm started by J.B. Pritzker, a Democratic mega-donor and candidate for governor in Illinois.
Nicholson reported last month that he had been paid at least $15,000 from Pritzker-related companies over the past two years.
Nicholson is running against Republican state Sen. Leah Vukmir in the primary, with the winner taking on Democratic Sen. Tammy Baldwin.
Nicholson works as a business consultant for the Chicago firm ghSMART. He reported income from the Pritzker companies in filings last month.
Nicholson spokesman Brandon Moody did not address that work specifically, but said Monday that Nicholson has been "working hand in hand with the Senate Ethics Committee" to fulfill his reporting requirements.
Vukmir's spokesman declined to comment.
