DES MOINES, Iowa (Nov. 15, 2015) – Months of preparation at Drake University in Des Moines led up to last weekend's Democratic presidential debate.

But inside the debate hall, the finishing touches went up nearly to the final minutes. Crews were rehearsing Friday night when Paris came under attack.

“I think it was pretty obvious pretty quickly when we saw there were multiple locations,” Christopher Isham said, CBS News vice president. “That was  obviously red flags this was more than an isolated shooting.”

The debate would quickly shift focus and so too would the candidates.

“This is the nature of warfare,” O’Malley said Saturday morning. “This is not 20th century warfare. This is 21st century warfare.”

Behind the scenes, reports surfaced the Sanders camp was unhappy, voicing strong concern and opposition to CBS News executives, for the last-minute change.

Sanders shifted away from foreign policy when talking with FOX59's Matt Smith.

“We have to talk about how we handle the grotesque level of income and wealth related to inequality,” he said.

Democratic front-runner Hillary Clinton sent a team of aids Saturday afternoon including longtime confidant Huma Abedin.

“This is a turning point, everyone recognizes that,” Major Garrett said, CBS News Chief White House Correspondent. “Moments like this, as a candidate seeking the presidency, you have to inject something that is new, dynamic, possibly dramatic but that meets the moment.”
