Gov. J.B. Pritzker and his wife, M.K. Pritzker, reported more than $6 million in gross income last year, about $5.5 million of which was federally taxable, according to a nine-page summary of 2018 state and federal tax returns released by his campaign Tuesday. The governor’s campaign did not, however, release any tax return documentation regarding trust funds which benefit the Pritzkers.
