State Sen. Napoleon Harris has dropped out of the race to fill the seat vacated by Jesse Jackson Jr. and will back former state Rep. Robin Kelly.
"Even though I am ending my bid for Congress today, I am still committed to fighting for the same causes that led me to enter this race," Harris said.
Harris announced his decision to enter the special election in December.
Kelly said her campaign continues to build momentum because of her pledge to stop gun violence and get dangerous weapons off our streets.
"The voters of the second district deserve someone in Congress who they can trust to stand with President Obama to take on the NRA," Kelly said. "While some of my opponents have A ratings with the NRA, I couldn't be proud of my F rating and it's a record that I will take to Congress to fight for the families across Chicago and the Southland."
Robin Kelly was appointed chief administrative officer for Cook County Board President Toni Preckwinkle in 2011. She is a former state representative from Matteson, which is in the 2nd District.
