A Cook County Circuit Court judge in Chicago will hold a hearing Friday in a lawsuit seeking to keep Ted CruzRafael (Ted) Edward CruzWhatever you think the Alabama special election means, you’re probably wrong This week: Congress gets ball rolling on tax reform Week ahead: Senators work toward deal to fix ObamaCare markets MORE off the Illinois primary ballot.

The lawsuit was filed by Lawrence Joyce, a pharmacist and attorney, who is challenging Cruz's right to be president due to his Canadian birth, according to a local NBC affiliate.

"What I fear is that Ted Cruz becomes the nominee, come September, Congressman Alan GraysonAlan GraysonPennsylania Dems file ethics complaint against Rep.

Grayson has vowed to sue the Texas senator, saying he's "ineligible" to be president.

“I’m waiting for the moment that he gets the nomination, and then I will file that beautiful lawsuit saying that he’s unqualified for the job because he’s ineligible,” Grayson said in a radio interview in November.

“Call me crazy but I think the President of America should be an American."

Joyce, who is a supporter of Cruz rival Ben Carson, reiterated that it would be best for the GOP to avoid a situation where the Democrats could sue their presidential nominee.

"What Democrats will do at that point is cherry pick which county courthouse they are going to show up in order to file these petitions," he said. "And that point, I fear they'll get a string of victories in the lower courts and the funding for Ted Cruz would dry up, his numbers would plummet in the polls, he may be forced to give up the nomination."

"I tried to talk myself out of it and was unable to do so. It's plain as day that Ted Cruz is not a natural born citizen of the United States," Joyce added.
