Democratic state Sen. Daniel Biss says he's running for Illinois governor in 2018.
In an online announcement, Biss on Monday became the latest Democrat to announce he's seeking the nomination to challenge Republican Gov. Bruce Rauner.
The former math professor from Evanston says people in Illinois "are hurting because of the failed policies of the last two years."
Biss led an attack on Rauner and other Republicans during the 2016 election, creating a super PAC that ran ads linking them to then-presidential candidate Donald Trump.
The Illinois Republican Party says Biss has supported Democratic House Speaker Michael Madigan and would be "the North Shore branch of the Madigan machine."
Other Democrats who've already announced they're running include businessman Chris Kennedy and Chicago Alderman Ameya Pawar. Billionaire businessman J.B. Pritzker says he's exploring a bid.
