On Sunday, Rubio staffer Joe Pounder posted this tweet, suggesting Ted Cruz's communications director, Rick Tyler, posted an article containing false information about Rubio.

The article claimed Rubio leaned over the staffer and said, "Got a good book there... Not many answers in it, especially that one," and that the Cruz campaign said the book was a Bible.

Thank you @rickwtyler for deleting this tweet peddling garbage. Should probably delete FB post as well pic.twitter.com/J4Ga6yXJqs — Joe Pounder (@PounderFile) February 21, 2016

On Monday, Tyler posted an apology on Facebook:

"I want to apologize to Senator Marco Rubio for posting an inaccurate story about him here earlier today. The story showed a video of the Senator walking past a Ted Cruz staffer seated in the lobby of a hotel reading his Bible. The story misquoted a remark the Senator made to the staffer. I assumed wrongly that the story was correct. According to the Cruz staffer, the Senator made a friendly and appropriate remark. Since the audio was unclear, I should not have assumed the story was correct. I've deleted the post because I would not knowingly post a false story. But the fact remains that I did post it when I should have checked its accuracy first. I regret the mistake."

The original article that was posted can be seen here. It's difficult to hear what Rubio said and see what the Cruz staffer was reading.
