A refreshed Sen. Marco Rubio says 'I needed water'

(CNN) -- Sen. Marco Rubio continued to poke fun at himself Wednesday morning after his now-famous sip of water made a big splash during his Republican response to the State of the Union.

Asked about the water on a morning news show, the junior senator from Florida reached over--out of the shot--to grab a water bottle and take a swig.

"I needed water. What am I going to do, you know?" he said on ABC's "Good Morning America."

"It happens," he continued. "God has a funny way of reminding us we're human."

Rubio could be seen wiping drips of sweat off his face a few times during his 15-minute response Tuesday night. Then at one point, he paused and lunged sideways--still looking at the camera--to grab a small bottle of water and take a sip.

The senator himself acknowledged the awkward break on Twitter afterwards, and the dry-mouth moment instantly went viral.

Rubio was asked on CBS' "This Morning" if he was nervous.

"No, when you talk a lot, it happens," he said.

During speeches with podiums, he added, speakers normally have some water right there in front of them.

"When you're standing up in front of a camera, you don't have that option," he said. "It had been a long day at work. I already taped an 18-minute speech in Spanish, so I'm just glad the water was nearby, I don't know what I would have done without it."
