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."
