Cruz issued the following statement on Monday night, according to Fox News Latino:
"The facts of my birth are straightforward: I was born in 1970 in Calgary, Canada. Because my mother was a U.S. citizen, born in Delaware, I was a U.S. citizen by birth. When I was a kid, my mom told me that I could choose to claim Canadian citizenship if I wanted. I got my U.S. passport in high school.
Because I was a U.S. citizen at birth, because I left Calgary when I was 4 and have lived my entire life since then in the U.S., and because I have never taken affirmative steps to claim Canadian citizenship, I assumed that was the end of the matter. Now the Dallas Morning News says that I may technically have dual citizenship.
Assuming that is true, then sure, I will renounce any Canadian citizenship. Nothing against Canada, but I'm an American by birth and as a U.S. Senator, I believe I should be only an American."
