"I think it is no surprise to anybody that John McCain is going to be supporting Marco Rubio in this election," Cruz told Bloomberg's Mark Halperin on "With All Due Respect."
 
"It's no surprise at all that he's trying to do what he can to help the candidate that he's favoring who he thinks shares policy positions with him," Cruz added. 
 
McCain, who faced similar eligibility questions during his 2008 bid, argued during a local radio program in Arizona on Wednesday that there is a difference between him and Cruz.
 
Cruz was born in Canada to an American mother. McCain was born on a U.S. military base in Panama. 
 
"So I think there is a question. I am not a Constitutional scholar on that, but I think it’s worth looking into. I don’t think it’s illegitimate to look into it," McCain said.
