Florida Sen. Marco Rubio's Republican response to President Barack Obama's State of the Union address included an impromptu water break to quench his thirst.

Rubio appeared to wipe away sweat during his rebuttal from the Speaker's conference room in the U.S. Capitol shortly after Obama's address. At one point, Rubio reached out with his left hand and took a quick swig of water from a small Poland Spring water bottle.

The brief sip of water lit up social media outlets such as Twitter, with people commenting on Rubio's thirst.

Garrett Jackson, Mitt Romney's personal aide during his 2012 presidential bid, tweeted that he "would have had that water bottle closer, had it been the Gov. Haha. Marco needs an aide."

Rubio tweeted a photo of the water bottle.
