CNN -- Senator Marco Rubio's response to President Obama's State of the Union address has gone viral.
But it's not because of what he said.
Instead, it's because of the sip he took from a bottle of water.
And lots of people are weighing in on his beverage choice-- including the D-C Water and Sewage Authority.
It released a statement saying that, in a blind taste test, most people thought tap water tasted better than the bottled stuff.
That, or they couldn't tell the difference.
The water company added that a thousand gallons of tap water costs about 10 dollars... while the same amount of bottled water would run you about a thousand dollars.
The agency says next time, Rubio should consider quenching his thirst with "reliable, affordable tap water."
