Hofstra University spokeswoman Karla Schuster said in an email to NBC 4 New York, "These tickets are not official tickets to the debate. They were printed at the last minute to create a souvenir for the students. We'll be reprinting them for all those who won tickets."
The commemorative tickets were the ones that featured the spelling error and not the official ones, said a Commission on Presidential Debates spokesman. He did not say who printed the tickets with the error.
