CBS put the awkward moment as this:
"Rubio, who had mopped his brow a few times previously during the speech, was in the midst of maligning what he called "false choices" Mr. Obama laid out between big government and big business. But he interrupted his thought to grab a small water bottle apparently at his side, ducking down and nearly out of of the camera frame, before taking a sip and continuing with his remarks."
What Rubio didn't realize was that this little tiny goofy momentduring his response to the SOTU speech would be something that would lead the news not just the next day BUT would be a Twitter moment archived in the clouds for the rest of his life.
I FB'd about it when it happened, saying that it would be the gaffe that led the news.
Many others tweeted and FB'd about it, too.
Awkward, awkward, awkward.
