he was comparing himself to john kerry, barack obama, two people who republicans outwardly despise, and saying that he should be cut slack because no one talked about them not showing up. he then blamed obama for not getting anything done later on.. likely due to, to them, not showing up. not looking good for him.
You missed Rubio's point. He was calling the Sun media hypocrites because they never called out those people but were quick to call him out. THAT is why big media is ****!
