Londrigan came within a percentage point of defeating Davis in the 2018 general election.

A continuing point of conflict between the Davis and Londrigan camps has been Londrigan’s pledge not to take money from corporate political action committees.

Carly Atchison, regional press secretary for the National Republican Congressional Committee, said that during the report period, Londrigan took $20,500 from PACs that accept corporate money — including funds of U.S. Reps. Bill Foster, Brad Schneider and Mike Quigley. All are Illinois Democrats.

“Betsy Dirksen Londrigan is a hypocrite when it comes to taking corporate PAC money,” Atchison said, adding Londrigan should “return every penny” of the $20,500 or “come clean” about who is really funding her campaign.

End Citizens United, a group that has endorsed Londrigan, said that Davis took $86,500 from corporate PACs, including $8,500 from PACs associated with pharmaceutical and health insurance companies, in the fourth quarter. The group said in all of 2019, 21 percent of Davis’ contributions, or about $400,000, came from corporate PACs.

The Washington, D.C-based group’s executive director Tiffany Muller said there is a difference between a candidate taking directly from corporate PACs and taking from congressional leadership PACs that take corporate money.
