According to a story in the Chicago Sun-Times, Chicagoan Henry Foster donated $500 and thinks the former Illinois congressman owes him a refund.

Foster quoted Schock as saying, “for those whom I’ve let down, I will work tirelessly to make it up to you,” according to the story.

“With this lawsuit, Schock has an opportunity to do just that by refunding campaign contributions,” Foster wrote.

In his lawsuit, Foster said that he donated money to Schock’s campaign because he thought Schock was “ethical, a breath of fresh air in Illinois politics, and had a bright future in Congress.”

Hey, buddy. You donated to a Republican. You get what you pay for.
