Supreme Court nominee Neil Gorsuch apologized for using the term “undocumented alien” during his Senate Judiciary committee hearing on Tuesday and clarified that he misspoke and meant “undocumented immigrant.”

Under questioning from Connecticut Democratic Sen. Richard Blumenthal, Gorsuch was telling an ancedote about ethnicity and sentencing when he used the phrase “undocumented alien” before stopping himself and saying “immigrant, sorry.”
