Not once.  Nah.. he never said that...

"However, the story doesn’t cite one speech where Rubio actually said that."

Man, Erick Erickson sure is stupid, isn't he?  As you can easily see on the video, Rubio has told that lie many times. How hard would it be for Erickson to find out what he was writing wasn't true?  I found that video in 30 seconds.  Of course, he is writing for, 'Human Events', and their audience is not interested in the facts.
