Obama aide: Ebola will be stopped 'at its source'

Senior White House adviser Dan Pfeiffer on Sunday defended the Obama administration's responses to a number of recent crises, arguing it is being proactive to stop Ebola "at its source."

"We've been preparing for this eventuality since the outbreak in West Africa started seven months ago," Pfeiffer said on NBC's "Meet the Press."

He said the White House was responding well to crises from Ebola to the Secret Service's problems to a number of other issues.

"I do understand that people have a growing skepticism of institutions for a long time, including government. But people should know that in every one of those situations you mentioned, where a problem arises we deal with it quickly, we deal with it forcefully to make sure it doesn't happen," he said.

When pressed on whether it was being too reactive rather than proactive, Pfeiffer fired back, saying administration officials are acting to stop Ebola in Africa before it becomes a problem in the U.S.

"That's exactly what we're doing. The only way to deal with is to stop it at its source," he said.
