Give me the quote where Cruz lied. To be a lie it has to be factually incorrect and he had to know it was factually incorrect.
He had to apologize for it so he knew it was a lie. If he didn’t before he let his camp spread it, then he’s too incompetent to check things out or pick good people to work for him.
