Candidates vying to replace former Congressman Jesse Jackson Jr. began filing paperwork Thursday morning with the Illinois Board of Elections.
Ald. Anthony Beale, Sen. Toi Hutchinson, former Rep. Robin Kelly, incoming Sen. Napoleon Harris and Clifford Eagleton met the 8 a.m. deadline to be eligible for a drawing that determines the top ballot spot for the special Feb. 26 election.
The filing period for established party candidates ends Monday.
Jackson resigned in November after holding the seat for about 17 years. He cited his health and acknowledged that he is under federal investigation.
The general election for the seat is April. 9. Several candidates have stepped forward, including Debbie Halvorson and Mel Reynolds. Both have served in the U.S. House.
