CNN — Lest any questions remain about Sen. Ted Cruz's national allegiance, the Texas Republican announced Monday he was renouncing his Canadian citizenship.
Cruz was born in Canada to an American mother and a Cuban father, and over the weekend he released his birth certificate to put to rest any questions about his background. In an analysis, the Dallas Morning News speculated Cruz - considered a potential candidate for the 2016 GOP presidential nomination - was a dual citizen of the United States and Canada.
"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," Cruz wrote in his statement.
"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," he continued. "Nothing against Canada, but I'm an American by birth, and as a U.S. Senator, I believe I should be only an American."
As speculation ramps up about Cruz's political future, some have questioned his eligibility to become president. Most legal experts have said Cruz qualifies as a "natural born citizen," a requirement for the White House job, as stated in the Constitution.
In the Dallas Morning News Sunday, legal experts told the paper that Cruz is not only eligible for president in the United States, he's also technically a Canadian citizen and can even run for Parliament. Unless he renounces his citizenship there, he could also obtain a Canadian passport, according to the newspaper.
The senator's office, however, said Cruz has never embraced his legal rights in Canada.
"Senator Cruz became a U.S. citizen at birth, and he never had to go through a naturalization process after birth to become a U.S. citizen," spokeswoman Catherine Frazier told the newspaper. "To our knowledge, he never had Canadian citizenship, so there is nothing to renounce."
