"They were using the campaign as their own personal piggy bank, and we are saying there are people out there who don't even have houses and don't have shoes, don't have food," said Marcus Lewis, candidate in the 2nd Congressional District.
Lewis says it is time for Jackson to resign before the November election. The U.S. Postal Office employee is running as an independent against Jackson
Also on the ballot is Republican Brian Woodworth. The Bourbounais resident says the voters should decide if they have had enough of Jackson.
"Frankly, the voters put him on the ballot. And I think it's going to be up to the voters for them to decide, is this is acceptable," said Woodworth.
The voters have not seen or heard from Jackson in four months. Jackson stopped working on June 10th, although his staff waited for two weeks before telling the public he was being treated for bipolar disorder.
The latest reported federal investigation into Jackson's campaign finances is separate from the previous probe about the sale of Barack Obama's Senate seat.
Despite his problems, political experts say Jackson will be re-elected.
"Jesse Jackson Jr. has no chance of losing his seat before this election. The voters will turn out and they will support him. He's a Democrat and they will be loyal to a Democrat no matter what," said Laura Washington, ABC7 political analyst.
While some Jackson supporters remain loyal, others are done with him.
"I don't think he is serving us right now, and we need someone here to represent us," said Sara Haddon, voter.
"He is justified in doing what he has done so far. I don't see any reason why I should not vote for him," said Willie Wilbon, voter.
"I really don't think he should stay on the ballot, because right now he has too much on his plate," said Dharon Davis, voter.
A few days ago, Alderman Sandi Jackson said her husband's name will stay on the ballot. ABC7 Chicago was unable to reach her for comment.
A spokesperson for the congressman said he has no comment about the Wall Street Journal report. A Justice Department spokesperson said it is not the department's policy to confirm or deny investigations.
