At a news conference today, Julie Pace, of the Associated Press, asked President Barack Obama about an unapproved drug used on two American Ebola patients.

Pace asked if he is considering sending supplies of the unapproved drug to West Africa.

“I think we’ve gotta let the science guide us,” he said, explaining that all of the information isn’t in on this drug.

However, he said Ebola “can be controlled and contained very effectively if we use the right protocols.”

Pace then asked if he would fast-track the drug’s use in the U.S. if it’s proven effective.

Obama said it’s premature to say, and he doesn’t have enough data to offer an opinion.
