As a legal matter, my mother is an American citizen by birth.

In this quote, Ted Cruz is addressing a legal point regarding his mother’s citizenship status. He states that, as a legal matter, his mother is an American citizen by birth, implying that she was born in the United States or to American parents and thus automatically acquired citizenship under U.S. law. Cruz’s statement is part of a broader context in which questions about his own eligibility for the presidency were raised, particularly related to his birth in Canada and his mother's citizenship.

The origin of the quote comes from the controversy surrounding Cruz’s eligibility to run for president in the 2016 U.S. election. Some questioned whether his Canadian birth disqualified him from holding the office, citing the natural-born citizen requirement in the U.S. Constitution. Cruz responded by emphasizing his mother’s American citizenship, asserting that he met the constitutional criteria because he was born to an American citizen.

Cruz's statement draws on the principle of birthright citizenship, which is enshrined in U.S. law. According to the 14th Amendment and other legal provisions, individuals born to American citizens are considered natural-born citizens, regardless of where they are born. By invoking this, Cruz asserts that, legally, his mother’s citizenship status ensures his eligibility.

Ultimately, Cruz’s remark was part of a legal defense against claims that his birth outside the U.S. might affect his qualifications for office. He framed it as a straightforward legal matter, emphasizing that the law is clear about the citizenship status of individuals born to American parents, regardless of the country of their birth.
