In the behind-the-scenes interview, Gibbs described the president's "3 a.m. wake-up call" moment last April, when word came in the early morning hours that the North Koreans had conducted a nuclear missile test.
"We all were in a room in - on the first foreign trip in Prague in the Czech Republic - when we were notified of the North Koreans testing a long-range missile, something we'd expected to happen over a certain amount of time," Gibbs said. "And I think it was about 4:00 in the morning we were in there and we then discussed that and I went to wake him up and he soon joined all of us in getting intelligence briefings from in the room as well as back in D.C."
Axelrod said Obama proceeded to get "a read up on the military people, [get] on the line with Secretary Gates, General Cartwright I think. And then he says, "OK, here's what we're going to do."
The full interview is set to air Monday throughout The Situation Room beginning at 4 p.m. ET.
