"I think that [Donald] Trump is brilliant to raise this issue. When my son, Gabriel, and his wife, Deb, was pregnant, I said, You got to come home. I want my grandson to be president of the United States. He has to be born in the United States.Now, a child of a citizen of the United States born abroad or born wheresoever is a citizen if that's - he or she so chooses. So there's no doubt but that Ted Cruz is a citizen of the United States."
