A challenge had been filed in the state election division of Indiana that was denied today.
And in court papers filed by two voters in New York state court this week, a complaint argues that Cruz should be struck from that state’s primary ballot because he “is not a natural born citizen of the United States.”
Cruz was born in Canada to an American mother and has repeatedly maintained that he is a "natural-born citizen" as is required by the Constitution to run for president.
Trump has threatened to sue Cruz over his eligibility to be commander-in-chief. "He is welcome to file whatever lawsuit he wants," Cruz said in a CNN Town Hall Wednesday night.
The Cruz campaign did not respond to the latest lawsuit, but said at the Town Hall that his "mother was born in Wilmington, Delaware. She is a natural-born citizen. I was born in Canada."
Most legal experts contacted by ABC News say that Cruz would almost certainly meet the definition of a natural-born citizen and therefore would be eligible for the presidency. But the matter has not been decided with finality by the courts.
The lawsuit in New York does not target Cruz directly but rather seeks an order from the court that the New York State Board of Elections not designate Cruz a candidate.
In the Vermont suit, a man named Brooke Paige said Cruz does not meet the “natural born Citizen qualification set forth in the U.S. Constitution.”
In Utah, the challenge comes from a voter named Walter Wagner who argued “Having an unqualified candidate compete with the numerous qualified candidates potentially skews the results.”
ABC News has reached out to the Cruz campaign for comment.
