A Chicago judge is expected to hear testimony Friday in a lawsuit alleging that Republican presidential candidate Ted Cruz should not be allow to run for the White House. Illinois voter Lawrence Joyce will have his case heard in Cook County Circuit Court. Joyce objects to Cruz’s placement on the Illinois primary ballot next month over the Texas senator’s Canadian birth, according to CNN. His previous objection to Cruz’s eligibility was filed with the state’s Board of Elections and was dismissed. Cruz maintains he’s a natural-born citizen as his mother is American-born. “My case presents the perfect opportunity for Donald Trump himself to step forward and bring the matter to court personally,” Joyce told WBBM radio. However, Joyce said he has not spoken to the Trump campaign and is supporting Ben Carson.
