Cruz has stated that when he was a child, his mother told him that she would have to make an affirmative act to claim Canadian citizenship for him, so his family assumed that he did not hold Canadian citizenship.[140] In August 2013, after the Dallas Morning News pointed out that Cruz had dual Canadian-American citizenship,[141][142] he applied to formally renounce his Canadian citizenship and ceased being a citizen of Canada on May 14, 2014.[140][143]
Cruz ran for Senate in 2012. If he had disclosed his dual citizenship it wouldn’t have come up in August of 2013.
